About PressPerCent

PressPerCent project started around 20 years ago as a simple ink key pre-setting software tool — a popular subject at the time when printing press manufacturers and printers were searching for less expensive, space-saving solutions to replace hardware plate scanners. Since then PressPerCent evolved to include more features the customers and OEM partners required such as support for the job format of dozens press types and models, total ink calculations, spot color preview, automatic job processing and flexible press configurations.

Made for the graphic arts industry standard Apple Macintosh computers, PressPerCent evolved with the Mac OS operating systems. The application that once ran under classic Mac OS 8 and was closely integrated with the Adobe Acrobat package now takes advantage of Mac OS X built-in PostScript conversion and PDF rendering features. The current version of the application works with 10.6 (‘Snow Leopard’), 10.7 (‘Lion’), 10.8 (‘Mountain Lion’), 10.9 (‘Mavericks’), 10.10 (‘Yosemite’) and 10.11 (‘El Capitan’) system versions (a separate build for Mac OS X 10.4 (‘Tiger’) and Mac OS X 10.5 (‘Leopard’) is also available).

PressPerCent features

1. Ink key pre-setting

PressPerCent calculates area covered by the image on the plate for each ink zone of the printing press. The result is adjusted with user defined calibration curves for specific press models or ink/paper combinations and could be used as ink zone (ink duct) settings for the press. These settings could be displayed on screen, printed out on paper or exported to variety of file formats.

Press operators can use the settings to preset ink keys on the press console when the job changes. This can improve make-ready times and reduce paper and ink waste. The accuracy of pre-settings depends on press conditions and the zone curve's calibration quality.

2. Area coverage calculation

PressPerCent calculates not only individual zone coverage, but also the coverage for the entire area of the plate. Knowing this value helps estimate the amount of ink required to print the job. This feature would also be beneficial to packaging printers with flexographic equipment (to calculate amount of Pantone inks for the job) or even to digital printers (to quote the price based on a toner consumption).

If you only need to know the area coverage for a job without ink zone information just toggle the check boxes in PressPerCent preferences to switch off the zone calculation and display.

3. Maximum total ink check

Even if it is too late to re-separate photos or change vector graphics of the job when the plates are ready, the printer should pay attention to the maximum Total Ink warnings and take steps to avoid the problems: reducing the speed of the printing press, choosing different paper stocks or asking for another set of plates.

PressPerCent calculates maximum total ink value for each sheet of the job and shows the problematic areas based on user defined size settings (to ignore control bars and registration marks that may exceed maximum total ink without negative effects).

4. Export plug-ins

Almost every printing press made since the early 90's can either save printed job settings to a file (on network or removable media i.e. floppy disks) or load image area information from files prepared by plate scanners.

Proprietary job file formats can be quite different for each press manufacturer, press model or even press console version. Some presses use plain text files that are easily readable and understood by people. Others use binary data that requires more efforts to interpret it. Few press consoles may even show the press operator a preview images of the job prepared by the pre-setting software. This helps to identify and load jobs more quickly. Despite these differences, all press file formats convey the same common information: ink keys and ink feed (ink sweep) settings for each unit of the press or ink zone area calculations performed by a plate scanner.

PressPerCent uses this similarity of press file formats and supports different press models via the export plug-ins mechanism. The export plug-ins are small modules that save common information prepared by PressPerCent in a specific file format understood by this or that press console. This approach extends support for various presses without constantly modifying the application for each press or overloading it with code and features other users will not need. Just add to the application the plug-in for your press from optional plug-ins set. If you cannot find your press in the plug-ins set or you need a different plug-in version, please, contact us and we will try to create a new plug-in for you.

5. Incoming job formats support

PressPerCent supports the following file formats for incoming jobs: PostScript, PDF, TIFF and PPF.

If a job arrives as a PostScript file it will be converted to PDF with a built-in Mac OS X normalizer (or with Adobe Acrobat Distiller if Adobe Acrobat package is installed). TIFF files could be either 1-bit or 8-bit (low resolution previews) made by the RIP. For PostScript and PDF jobs with spot colors we suggest that you use pre-separated files to avoid possible problems with color separation.

However, the best choice of incoming job file format for PressPerCent is CIP3/CIP4 PPF (Print Production Format).

6. CIP3/CIP4 Print Production Format (PPF)

The new JDF/JMF formats for "seamless integration of CRM, MIS, prepress, press and postpress" being developed by CIP4 consortium looks promising for the future of the industry. The older PPF format well defined back in 90's already delivers certain benefits today.

Unlike JDF, the PPF format does not require sophisticated workflow software to be produced or interpreted. The PPF format is more simple and ‘hardware independent’ than JDF. The PPF file created by the prepress system does not contain actual ink key settings or press unit specific information (as JDF may have). It has only a low resolution image of the plate that will be processed into ink keys by some pre-setting tool or advanced press console. Due to the simplicity and fewer steps required to implement, the support for the PPF format was included into the products by almost every prepress RIP vendor and many printing press manufacturers.

PressPerCent can work with the PPF format in every way. It can import a PPF file made by your RIP or workflow, display the job on screen and calculate ink key settings for your press. It can also export a PPF file from a PDF or TIFF file of the job. You can send this PPF file to a different software tool that calculates ink key settings for your press or directly to the press console, if it supports that format.


7. Spot and paper color preview

It is always a demanding task to predict the exact results of printing with spot colors, especially with tricky inks like varnish or metallics where the order of printing units may have severe effects on the final output. Printing on colored, tinted or metallic paper presents a similar problem.

In PressPerCent a user can define the order of inks and their units assignment, specify if the ink is transparent or opaque and choose the paper color. If the job is printed in several runs (on a two color press, for example) the output of each run could be previewed or printed.

8. Hot folders automation

Every production site has its own workflow that is based either on a sophisticated prepress software system or just on a single, stand-alone RIP that completes the job from processing incoming PDF or PostScript impositions to controlling plate production on a CtP device. Whichever you use, if the workflow supports the automatic export of TIFF or PPF files to a folder on the network file server PressPerCent could be integrated onto it.

PressPerCent can periodically scan the user defined "Hot Folder", process incoming files and export the ink presets into another folder for the next step of your workflow. Any number of hot folders with different press and job options can be set up.

Download PressPerCent

To download PressPerCent use the link below:

presspercent345.dmg (Version 3.4.5, 35.1 MB, Disk Image)

System requirements: Apple Macintosh with Mac OS X version: 10.6 (‘Snow Leopard’), 10.7 (‘Lion’), 10.8 (‘Mountain Lion’), 10.9 (‘Mavericks’), 10.10 (‘Yosemite’) or 10.11 (‘El Capitan’). Internet connection is required for software activation.

There are two application versions on this disk image:

  • ‘PressPerCent’ is the main application version for computers with Mac OS X 10.6 and above. This version contains 32/64-bit Intel code only.

  • ‘PressPerCent (for Mac OS X 10.4-10.5)’ is additional 32-bit Intel/PowerPC Universal Binary version for Mac OS X 10.4 and 10.5. This special application version was built mostly for those printers who have legacy PowerMacs G4/G5 with still working motherboards and power supplies. We do not recommended to use this build on computers running Mac OS X 10.6 and above. It will not run on OS X 10.11, if you have modern Mac hardware, please use normal ‘PressPerCent’ version instead.

Details: This is Mac OS X disk image created with Disk Utility application. If you are using non-Macintosh computer to access internet resources, download the file and transfer it to Macintosh with Mac OS X system.

This is full working version of PressPerCent application. However, until you purchase the license and enter correct serial number (that will be sent to you via e-mail after purchase), PressPerCent works in Demo mode. The difference from registered version is that you can not modify printing press sheet dimensions to match your press making it somewhat unusable for real production purposes. Demo mode allows you to test PressPerCent in your workflow environment.

Upgrade Policy

In May 2011, after more than 10 years of selling PressPerCent licenses online, we decided to introduce some means that will allow us to estimate number of active PressPerCent users we actually have. So, we decided to introduce ‘upgrade terms’ for users who purchased PressPerCent license many years ago and would like to upgrade to the latest version. (It should also help us to collect some small funds for future PressPerCent development):

    1. Those users who purchased PressPerCent license less than 5 years ago get all version updates and upgrades for free (without any additional fee).
  • If you purchased PressPerCent less than 5 years ago and the serial number you have does not work (for some reason) with the latest application version, please, send us e-mail to info@excourse.com.

  • 2. Those users who purchased PressPerCent license 5 years ago or earlier may renew their license and update their serial number for the latest application version for small additional fee of $50.
  • To renew PressPerCent license purchase ‘License Renewal for PressPerCent’ product from our order page at Kagi.

  • 3. License renewal is good for another 5 years term of free updates and upgrades.

Note: This is not any kind of ‘subscription’ and it does not mean that your existing PressPerCent license becomes ‘invalid’ after 5 years of usage. You can use it as long as you like for as many years as needed. It just limits the ability to receive free upgrades to current modern versions to 5 years since purchase (or renewal) date.
