1. 5/1/2003KWitte Triangle Digital TRIANGLE DIGITAL Updating Media Models TO TRIANGLE DIGITAL INk

2. 5/1/2003KWitte Triangle Digital What are Media Models?  Mathematical descriptions of Resolution, Speed, Ink and Substrate

3. 5/1/2003KWitte Triangle Digital Why Update Media Models?  Triangle Digital uses higher quality pigments creating a large color gamut and 30% more longevity.  By Updating the Media Models you bring your printer to a neutral gray scale and adjusted ink limits for consistent color and dry times.

4. 5/1/2003KWitte Triangle Digital How long will this take?  To “Update” a current media model will take about 15 minutes  To build from scratch will take about 45 minutes  This does not include loading the various medias.

5. 5/1/2003KWitte Triangle Digital What is the difference between Media Models and ICC profiles?  Media Models are the foundation to creating a ICC.  Media Models include Dark Ink restriction, Linearization and Ink Limits  These are all related to the ink, media, speed and resolution of your printer.

6. 5/1/2003KWitte Triangle Digital Getting Started  Bench Mark your printer  This establishes how your printer is currently.  Attach Reading Device  DTP41, SpectroLino  Launch Calibration module in Onyx

7. 5/1/2003KWitte Triangle Digital Bench Mark Printer  Overall maintenance of machine  Age of filters  Cleanliness of printer and surrounding area  Composite image  Print on main substrate  Print at all speeds used  Make sure all nozzles are working  Keep prints to compare to new Settings

8. 5/1/2003KWitte Triangle Digital Bench Mark Printer….  Analyze the prints  Look for fish eyes (too much ink)  Color shifted grays (printer not linear)  Choppy Gradation (poor transition from light colors to CMYK color)  Poor Blacks or Shadows (too much GCR or ink too limited)  Reds, Green, Blue shifted tone (printer not linear)  Make note on print then set aside

9. 5/1/2003KWitte Triangle Digital Launch Calibration software  Click on the printer icon upper right corner,  Select the printer, media, ink set and resolution you want to update

10. 5/1/2003KWitte Triangle Digital Linearization  Click on White paper w/Yellow Plus  Launches Wizard  Create “New Profile”  Linearization Table  Print Swatch  Select Device Setup Device to serial port  Print  This will launch right into Rip Center

11. 5/1/2003KWitte Triangle Digital Read Linearization Strip  Double check patches  Make sure patches are dry  Limited banding  Back to Media Manager  Continue Wizard to read in Patches with X-rite DTP-41

12. 5/1/2003KWitte Triangle Digital Build Linearization Drag each Color line to reach 100% Check “Swatch Measurements” for spikes or flat lines. If OK press Build to create profile.

13. 5/1/2003KWitte Triangle Digital Create Ink Limit  Click on White paper w/Yellow Plus  Launches Wizard  Create “New Profile”  Ink Limit  Print Swatch  No Device used  Print  This will launch right into Rip Center

14. 5/1/2003KWitte Triangle Digital Finish Ink Limit  Dry print in normal “Production” Dry time  Read Swatches by eye  Looking for Maximum 3 color and 4 color patches without bleeding or pooling  Feel right for sticky or tacky.  Media Manager  Type in limit (ie:3.05)  Above 3.00 allow GCR can be used  Onyx does not suggest going below 2.75

15. 5/1/2003KWitte Triangle Digital Check Output  Reprint Bench Mark Prints  Compare to first prints  Print should be neutral, good contrast even strong RGB-CMYK colors. If you notice that you are still a touch heavy in one color…  Tweak Linearization if necessary  High light Linearization right click and go to “Tweak”

16. 5/1/2003KWitte Triangle Digital Tweak Linearization Under Edit select the color that is too strong Press NFactor button. Reduce number by 10% Close window than build adjusted linearization Reprint repeat as necessary.

17. 5/1/2003KWitte Triangle Digital Tweak Ink Limit  Media’s change absorption  If you start to get fish-eyes lower your ink limit.  If your blacks are too flat raise your ink limit.  You can either tweak or create a new ink limit to adjust. HINT: Remember to let the product dry at production speed before reading strip
