Profile Prism v8.0 (Aug 13, 2013)

Overview:

Version 8.0 is fully Windows 8 compatible, features an updated (more modern dark gray) UI, and offers more accurate color when creating ICC profiles thanks to advancements in color technology over the last few years.  User friendly tips such as a warning to change old profile descriptions and automatic naming of modified (tweaked) printer profiles will help you along the way as you create the most accurate profiles to date!  Enjoy the subtle color improvements that result from the v7.0 --> v8.0 upgrade and the UI changes that make the software easier than ever to use.  If you print a lot of photos and you create and tweak printer profiles regularly, v8.0 will be well worth the upgrade.


Profile Prism v7.0 (11/08/10)

Overview:

Version 7.0 uses an all new color management engine that offers greater color accuracy and slightly faster performance.  This major upgrade builds upon Profile Prism's world renowned color accuracy by offering subtle improvements to color accuracy, particularly at the extremes of tonal range where you will see smoother shadow and highlight detail.  The already excellent profile developing and tweaking tools remain unchanged so there is no learning curve for existing customers: simply reopen your old target images and generate a new profile to get the improved color accuracy of v7.0.  Click here to go to the support page where you can renew your yearly membership (if you haven't already renewed in the past year) and download the latest version.


Profile Prism v6.5 (06/11/08)

Overview:

Version 6.5 offers new camera profiling options, slightly faster profile generation, and full Vista compatibility

New Features:


Profile Prism v6.0 (01/10/06)

Overview:

Version 6.0 offers more accurate profiles and a color tweaking wizard

New Features:

v6.0x Release History

Version Released Description
v6.01 01/17/06 v6.01 offers both an "OK" and an "Apply" button on the Color Tweaking Wizard so that changes can be accepted without forcing the main (editor) image to preview the changes, allowing further changes/tweaking before previewing the results.  This maximizes capability while minimizing screen update delays.
v6.02 01/23/06 The "Increase or decrease contrast" selection in the Color Tweaking Wizard mistakenly changed saturation instead of contrast in v6.00 and v6.01.  This has been fixed in v6.02.
v6.03 02/01/07 While no changes have been made to the software, the help file has been updated to include instructions for profiling digital cameras with the IT8 target.  The matte target has been discontinued and Profile Prism now ships with one target (glossy IT8) which can be used to profile all devices: camera, scanner, and printer.  After years of testing, we have determined that the accuracy of the glossy IT8 target is superior to the matte target, making the IT8 target a better choice for profiling all devices.  In addition, by following the updated camera profiling instructions, the glossy IT8 target can be used to profile cameras with no issues related to reflections or glare, so a matte surface is not necessary.  Discontinuing the matte target has also allowed us to keep Profile Prism at $79 instead of raising the price for 2007 to cover increasing R&D and material costs.

Profile Prism v5.2 (11/01/04)

Overview:

Version 5.2 contains functions that make the editor easier to use and more accurate

New Features:

Fixes:

v5.2 Release History

Version Released Description
v5.21 11/04/04 v5.21 resets the right test image in the editor window automatically when the "go back" function is used, making the behavior of the "preview" and "go back" functions more intuitive in this version.
v5.22 11/05/04 v5.22 includes the following:
  • Increased the resolution of adjustments by allowing fractional values. Sliders can still be used to adjust up/down to integer values but fractional values may be entered manually in the edit boxes to the right of the adjustment sliders to create higher precision (smaller) changes.
  • Corrected a bug that was causing adjustments to be doubled (added) if "Save Modified Profile" was used more than once from the editor without exiting/reentering the editor window.
  • Corrected a bug that was causing the "would you like to save" warning to appear even if you already saved the profile and made no changes since the save.
  • Corrected a bug that was causing slight posterization on certain types of gray scale adjustments. The correction may result in a need to make slight modifications to your previous gray scale adjustments if you choose to re-edit profiles created in earlier v5.x versions.
v5.23 11/05/04 v5.23 corrects some intermittent problems with the right test image on the editor window such as old and new images being superimposed on the right test image after using "File", "Open Test Image".
v5.24 11/06/04 v5.24 corrects the contrast slider on the editor so that it is no longer backwards; so that sliding to the right increases contrast and sliding to the left decreases contrast. There is no need to modify the contrast settings stored in your previous edits since they will be "flipped" automatically whenever you load an old/edited profile, thereby insuring the same results even though the contrast slider has been flipped to the correct orientation.
v5.25 11/09/04 v5.25 corrects a bug that was causing Profile Prism to crash with a "read beyond end of file" error message after opening certain 48 bit TIFF's from Vuescan.
v5.26 01/20/05 v5.26 offers a better method of making global changes to parameters like saturation, contrast, and brightness using the "apply changes" button. See the updated help near the bottom of this help page under the heading "the since last preview group and apply changes button".
v5.27 01/21/05 v5.27 fixes a glitch that was causing the main window to pop up on top of the editor window under certain conditions.
v5.28 05/18/05 v5.28 includes a color highlighting tool that highlights colors in the (left) test image in the profile editor when the mouse button is held down on a dot on the color wheel. This version also corrects some issues with the color dropper remaining active at inappropriate times when using the editor.
Profile Prism v5.1 (10/26/04)

Overview:

Version 5.1 corrects some minor issues with the profile editor and adds new functionality to the editor

New Features:

Fixes:

v5.1 Release History

Version Released Description
v5.11 10/26/04 v5.11 corrects a problem where the profile (file name) listed on the main window was not being loaded automatically in the editor unless the file name on the main window contained the "icm" extension. This version also associates the adjustment parameters with profiles in such a way that they can be retrieved for files in different folders such as c:\program files\prism\test.icm and c:\myprofiles\test.icm. This change is transparent to the user and simply ensures that two files named "test.icm" can have different adjustments if the files are in different folders.
Profile Prism v5.0 (10/22/04)

Overview:

Version 5.0 allows precise editing of printer profiles

New Features:

Profile Prism v4.4 (07/04/03)

Overview:

Version 4.4 supports both "perceptual" and "relative colorimetric" rendering intents for printer profiles

New Features:

Version Released Description
v4.41 07/04/03 v4.41 fixes an intermittent crash (access violation) that occurred at the end of the profile generation process when generating printer profiles from some scans.
v4.42 07/06/03 v4.42 generates profiles up to 20% faster than v4.41 while not compromising color accuracy.
v4.43 07/07/03 v4.43 enhances the red and blue gamut for "perceptual" intent to prevent reds from turning orange and blues from turning purple.
v4.44 08/18/03 v4.44 eliminates color smearing in shadow areas (dark colors). This change affects only printer profiles; camera/scanner profiles are not affected.
v4.45 09/18/03 v4.45 improves shadows in printer profiles when profiling printers with very dark output. Also added "printer profile usable range" message to give an indication of the quality of shadows in the test print and changed the print driver recommendations for Epson printers. v4.45 also has a new printer-target-40.tif file that has a black border to eliminate "light bleed" that tends to brighten color patches on the edge of the target. This minor change to the target can have a noticeable effect on profiles as we've found light bleed from the small white border can falsely brighten the outer color patches on many scanners.
v4.46 09/30/03 v4.46 includes a brighter printer target for profiling printers that produce output that is too dark to scan realiably (such as Epson printers in "no color adjustment" mode). Simply print the included "printer-target-bright.tif" and make the corresponding selection for "Printer Target" on the main window. See the updated help for more details. v4.46 also includes a slight improvement to blue gradients in printer profiles.
Profile Prism v4.3 (06/20/03)

Overview:

Version 4.3 renders higher quality printer profiles

New Features:

Version Released Description
v4.31 06/24/03 v4.31 corrects an issue that caused abrupt shifts to black in shadows with v4.3. v4.31 also tests your printer profile after it is created to determine if posterization (banding) exists due to abrupt shifts in color gradients. After examining the profile, adequate smoothing is applied to the profile to eliminate posterization artifacts.
Profile Prism v4.2 (06/05/03)

Overview:

Version 4.2 offers the ability to compensate for metamerism and ships with two reference targets: a standard IT8 reference target and a matte target for profiling cameras

New Features:

Fixes:

Version 4.2 Revision History

Version Released Description
v4.21 06/06/03 v4.21 produces slightly more neutral prints by approximating the amount of optical brighteners in the paper and compensating for the color of the paper versus predicted ink coverage. v4.21 also fixes a problem that caused some printer profiles to produce slightly oversaturated reds. Finally, v4.21 contains an updated printer-target-40.tif file that prints larger (7.92 x 5.77 inches) and contains a dotted line for cutting the target from the printed page.
Profile Prism v4.1 (04/28/03)

Overview:

Version 4.1 now shipping with IT8 reference target

New Features:

Starting with v4.1, Profile Prism will be shipped with an IT8 reference target rather than the older matte target. We have found that there are quite a number of loyal Profile Prism users who actually wear out the matte paper targets by taping and untaping, over exposure to ozone, UV, and finger oils, etc. We believe that the change to industry standard IT8 targets provides users with targets that are more durable and provide higher quality profiles over a longer period of time without the need to update/replace targets frequently. While IT8 targets do not allow for correction of lighting variance as do older PP targets, we believe that it is better to correct issues with lighting up front rather than attempting to correct them after the fact. In addition, the dot-free continuous tone color provided by IT8 targets eliminates any adverse interactions between image capture and dot patterns, improving reproduction of subtle colors such as gray scales and skin tones in profiles.

While v4.1 cannot automatically correct for lighting variances across the IT8 reference target, it does evaluate overall lighting variance and reports the amount of variance to the user. This allows the user to make change(s) to the image acquisition methods in order to improve lighting of the target in the original photo/scan. Note that lighting variance is more of an issue with camera profiling and is less of an issue when using scanners. Finally, recent improvements in Profile Prism software now allow incredibly accurate profiles using IT8 targets as the reference. We believe that the combination of revised profiling instructions (now separate for cameras, scanners, and printers) and use of more durable IT8 reference targets allows Profile Prism to achieve optimal profiling performance while at the same time being more cost effective.

IT8 targets now shipping with Profile Prism are also available for $15 to existing users (the same price as older targets) and may be ordered separately at http://www.ddisoftware.com/prism/ordering.htm. We also now offer IT8 targets on 35 mm slides for the purpose of profiling slide scanners.

Note: You may still use Profile Prism with your existing pp-10, pp-11, etc. reference targets, however, these targets are no longer offered for sale.

Version 4.1 Revision History

Version Released Description
v4.11 05/03/03 v4.11 includes the following:
  • "Jiggle corners" option now works on all targets, including the new IT8 targets.
  • Fixed a bug that was causing high "lighting variance" readings.
  • Updated the "good histograms" in the help file to correspond with the new IT8 and printer targets.
v4.12 05/14/03 v4.12 is now compatible with IT8 data files supplied by colour-science.com.
Profile Prism v4.0 (03/19/03)

Overview:

Version 4.0 features a quantum leap in printer profile accuracy and consistency

New Features:

IMPORTANT NOTE: If you are upgrading from a previous version to v4.0, you do NOT need a new reference target for v4.0! The pp-10, pp-11, etc. targets have not changed and your existing pp-10, pp-11, etc. reference target may still be used with v4.0. The 9,261 color patch printer target is included (as a TIFF file) with v4.0 and should be printed from your photo printing/editing software for profiling. This new printer target is then scanned with your existing Profile Prism reference target to produce the printer profile.

Version 4.0 Revision History

Version Released Description
v4.01 03/22/03 v4.01 fixes a problem that caused v4.0 printer profiles to render pure white with a slight color cast (usually pink/magenta) when using the profiles in PhotoShop. In addition, v4.01 fixes the "RGB bias" selections which were inadvertently "disconnected" in v4.0.
v4.02 03/31/03 v4.02 produces printer profiles with an expanded gamut which eliminates problems like blue/purple transitions. In addition, v4.02 will render smoother gray scales with better neutrality.
v4.03 04/07/03 v4.03 fixes a bug that caused corrupted profiles when using IT8 targets produced by Agfa or Wolf Faust.
v4.04 04/08/03 v4.04 improves rendering of deep/bright reds in printer profiles. The change does not affect camera or scanner profiles.
v4.05 04/09/03 v4.05 contains an adjustment to the rendering of deep/bright blues and reds in printer profiles. v4.05 produces a smoother and wider blue gradient while providing deeper reds without sacrificing skin tones and other colors.
v4.06 04/11/03 v4.06 contains an adjustment to bright yellows in printer profiles. In addition, the "Profile For" option is now enabled for printer profiling and allows selection of "Highest Accuracy" which produces the most visually accurate results or "Smoother Gradients" to produce more mathematically accurate colors with smoother gradients. See the help under "Profiling a Printer - Step by Step" for a full description of the "Profile For" option.
v4.07 04/13/03 v4.07 offers additional messages which are displayed after creation of printer profiles. The new messages (dynamic range and gamut coverage) assist users in evaluating the contrast and color range of different types of media. In addition, when profiles are created with v4.07 or later versions, the evaluation messages are saved and can be recalled using "File", "Recall Messages For". See the help under "Contents", "Profiling a Printer - Step by Step" and click "Final review of any additional messages" for full info on the new features. The purpose of v4.07 is to provide users with useful information about the media they are profiling. The actual profiles created by v4.07 will be identical to v4.06.
v4.08 04/15/03 v4.08 contains a more accurate pp-29.dat file. For those using the pp-29 reference target, reprofiling may lead to minor improvements in some profiles. The change only affects the pp-29 target, so if you use any other reference target, v4.08 will be identical to v4.07.
Profile Prism v3.7 (03/12/03)

Overview:

Version 3.7 features the ability to profile using IT8/Q60 targets and offers more accurate profiling

New Features:

Profile Prism v3.6 (01/03/03)

Overview:

Version 3.6 offers simple profile color "tweaking" ability

New Features:

Version 3.6 Revision History

Version Released Description
v3.61 02/02/03 v3.61 corrects an issue where not all target versions are visible in the dropdown under "Prism Target" on some machines.
Profile Prism v3.5 (12/09/02)

Overview:

Version 3.5 adds visual monitor calibration and improves tonal response of all profiles

New Features:

Profile Prism v3.2 (09/24/02)

Overview:

Version 3.2 further improves rendition of out of gamut colors in printer profiles

New Features:

Notes: If you already have scans that you used in v3.0 or v3.1, there is no need to rescan targets. Simply use your scan(s) that you used for v3.0/v3.1 and reprocess them with v3.2.

Version 3.2 Revision History

Version Released Description
v3.21 09/25/02 v3.21 fixes a bug in v3.2 that was disabling gradient smoothing for out of gamut colors, resulting in faint banding or "halos" in some bright, saturated colors. While v3.2 was able to generate relatively smooth gradients without any smoothing applied, the automatic smoothing in v3.21 will now render perfectly smooth color gradients even for colors that are not reproducible by the printer.
v3.22 09/27/02 v3.22 fixes an internal range error that was causing highlight blowouts or strange color shifts in bright, saturated colors under some conditions. The fix, which affects only the brightest and most saturated colors, affects both scanner and printer profiles. To find out whether (or to what degree) this fix will affect the bright, saturated colors in your own profiles, you must rebuild your profiles with v3.22 and evaluate the results. In general, the fix will have more impact on scanner profiles than printer profiles, but differences may be seen in both.
v3.23 11/11/02 v3.23 includes an updated DLL that allows Profile Prism to achieve slightly higher color accuracy in deep shadows. In most cases, the difference will not be noticeable, however, a slight improvement in rendering of gray scales is possible in some camera, scanner, and printer profiles.
Profile Prism v3.1 (09/19/02)

Overview:

Version 3.1 is designed to enhance printer profile performance when profiling a wider range of papers/inks such as those from third party manufacturers

New Features:

Notes: If you already have scans that you used in v3.0, there is no need to rescan targets. Simply use your scan(s) that you used in v3.0 and reprocess them with v3.1.

Profile Prism v3.0 (09/03/02)

Overview:

Version 3.0 offers a significant improvement in printer profile color accuracy

New Features:

Fixes:

Profile Prism v2.7 (08/21/02)

Overview:

Version 2.7 offers more accurate printer profiling

New Features:

Profile Prism v2.6 (07/02/02)

Overview:

Version 2.6 offers refined color matching to provide greater compatibility for a wider range of printers.

New Features:

Fixes:

Version 2.6 Revision History

Version Released Description
v2.61 07/08/02 v2.61 now automatically saves all profile settings and crop markers each time a profile is generated. When the same image of the targets is opened in the future, Profile Prism will display the date that the image was last used to develop a profile and will prompt the user to reload all settings and crop markers. The availability of this option means that each image/scan only needs to be set up and cropped once. Future profile generations from the same image/scan can be performed by simply loading the old settings and changing any desired parameters, then clicking "Create Profile". In addition to this usability enhancement, the help file has also been updated to indicate new recommended settings for Canon printers, specifically, setting the "Print Type" to "None" instead of "Photo".

Profile Prism v2.5 (06/17/02)

Overview:

Version 2.5 generates the most accurate profiles to date.

New Features:

Profile Prism v2.4 (03/28/02)

Overview:

Version 2.4 offers more neutral color when creating printer profiles

New Features:

Version 2.4 Revision History

Version Released Description
v2.41 04/03/02 v2.41 opens up the "White Balance" control for printer profiling, allowing the user to select whether neutral gray colors follow the white point of the paper (default) or true neutral tones that are independent of paper color. See Profiling a printer - step by step, profile details and parameters, white balance in the help for more details.
v2.42 04/08/02 v2.42 offers new tools that assist in evaluating the capture of color targets, such as the ability to detect partially clipped color patches, ability to locate and scroll through clipped patches, and a densitometer that displays valuable information about each color patch such as RGB color values, lighting variance, and more. For information on how to use the new tools, simply open the "step by step" section of the help (for either camera/scanner or printer profiling) and look at the end of "Step 2: Opening and cropping the target". The information regarding the new densitometer, how to scroll through clipped patches, and new information on clipping can be found just prior to the start of "Step 3".
v2.43 04/09/02 v2.43 has improved detection/messages regarding clipped color patches and a rewritten help section on the subject of capture range and clipping. v2.43 also fixes a problem where the clipping message was not being reset after loading a new image. v2.43 has no changes to the profile generation itself and will generate profiles identical to v2.42.
v2.44 04/13/02 v2.44 now supports 48 bit TIFF images and has a fix that ensures that min/max/clipped "X" markers appear properly on the printer target after a new scan is loaded.
v2.45 04/24/02 Significant changes made to the "Profiling a Printer - Step by Step" portion of the help file to make that section more precise and up to date. Changes include recommendations for specific print driver settings by brand, scanner settings for the capture of the targets, new information about when to use "printer-target-bright.tif", and other information that has been refined since the release of printer profiling in version 2.0. No changes whatsoever were made to the profile generation part of the software, so in technical terms, v2.45 is identical to v2.44 except for the help file and the "v2.45" version number.
v2.46 05/29/02 Made a change that will allow profiles to correct more abrupt color discrepancies. The result is that v2.46 can now generate more accurate profiles for printers that require more color "adjustment" such as printers with pigment inks or other printers where narrow/fine corrections are needed.
v2.47 06/03/02 v2.47 contains an updated color management DLL that provides slightly better precision for some of Profile Prism's internal color gamut calculations. The result is a slight increase in color accuracy.
v2.48 06/07/02 v2.48 includes another minor update to the color management DLL to ensure the highest level of accuracy. In addition, a small adjustment was made to the tone curves that results in slightly brighter highlights in printer profiles (camera and scanner profiles are unaffected). Other than this small change to highlights, changes to overall color rendering of v2.48 versus v2.47 are negligible.

Profile Prism v2.3 (03/20/02)

Overview:

Version 2.3 offers better color matching, faster profile generation and offers a new "brightness" parameter.

New Features:

Version 2.3 Revision History

Version Released Description
v2.31 03/21/02 v2.31 includes a new, brighter printer-target-bright.tif file that is very useful for printers that produce dark prints in their baseline (no color management) mode. While the new gamma corrected target is useful for printers that produce dark prints in raw mode, the old printer-target.tif file is useful for printers that have no true "raw" print mode, or those that gamma correct brightness even with color management turned off. See the printing the printer target and scanning the result help section for details on how/when to use the [now] two included printer targets.
v2.32 03/22/02 v2.32 fixes a problem where not all color patches were being considered when using the new "printer-target-bright.tif" image for printer profiling, resulting in reduced range reported in the "spectral sample range" message.

Profile Prism v2.2 (02/26/02)

Overview:

Version 2.2 offers even greater color accuracy and smoother color gradients across the entire color spectrum.

New Features:

Fixes:

Profile Prism v2.1 (02/08/02)

Overview:

This update offers new, smaller ICC profiles that have better color accuracy as well as diagnostic tools for developing better printer profiles!

New Features:

Version 2.1 Revision History

Version Released Description
v2.11 02/09/02 v2.11 restores target evaluation messages (exposure, white balance, etc) that were being overwritten/cleared by the new dynamic range evaluation in v2.1. Other than the restoration of these text messages, v2.11 is identical to v2.1.
v2.12 02/11/02 v2.12 includes some small changes to the format of ICC profiles generated by Profile Prism. The changes will ensure compatibility across platforms and between different ICC aware imaging software.
v2.13 02/21/02 v2.13 has new gamut mapping formulas that result in greater profile accuracy, especially in shadows and very dark colors. Although the visible difference is slight over most of the brightness range, you may notice that v2.13 opens up shadows and renders more accurate color in dark/shadow areas of photos. This version also generates all profiles about 20% faster and fixes a memory problem that caused prior versions to crash if numerous profiles were generated in one session without exiting.

Profile Prism v2.0 (01/31/02)

Overview:

This major release offers higher overall color accuracy and ability to create printer ICC profiles!

New Features:

Profile Prism v1.7 (01/07/02)

Overview:

Version 1.7 improves the accuracy of the tone (brightness) curves.

New Features:

Profile Prism v1.6 (11/19/01)

Overview:

Profile description now stored correctly as a null-terminated string. Prior versions had no null character which could cause some ICC software to "complain" about PP profiles.

Profile Prism v1.5 (10/23/01)

Overview:

Version 1.5 improves the "Jiggle corners" function and provides some minor fixes.

New Features:

Fixes:

Profile Prism v1.4 (10/18/01)

Overview:

New Features:

Profile Prism v1.3 (10/05/01)

Overview:

Version 1.3 focuses on providing better detection of clipping in target shots while giving a better description of how to handle clipping in the help file. v1.3 also creates profile that are slightly more accurate than older versions.

New Features:

Profile Prism v1.2 (10/04/01)

Overview:

Version 1.2 focuses on giving the user better tools/messages to evaluate their target shots prior to profile generation, and provides a smoother user interface. Profiles generated by v1.2 will be identical to those generated by v1.1, however, the enhanced evaluation messages will help users find possible problems with their target shots that might have passed all the tests in v1.1. Consequently, v1.2 can help generate more accurate profiles by ensuring that shots of the color target have appropriate white balance, exposure, etc. up front.

New Features:

Fixes:

Profile Prism v1.1 (10/01/01)

Overview:

Version 1.1 incorporates user suggestions and focuses on providing options that allow users to create more accurate profiles for a wider variety of conditions. Profiles generated by v1.1 will be slightly more accurate than those generated by v1.0.

New Features:

Fixes:
