Standard CMYK Testing File
Many RIPs tell you they print your CMYK, but actually change it to RGB, quietly in the background without telling you. They then change it BACK to CMYK, but what was once black-only has now become 4-color grey. Also, many RIPs don't suport the Postscript feature of overprinting. Therefore, you should test your RIPs.
If you do not have a CMYK image that you would like to use in the testing of your RIPs or for the testing your new advanced device links, select from the options below for our standard file.
We have three different testing files:
Click here for a already rendered CMYK TIFF.
Click here for a CMYK postscript file (with overprint) which is ready to send to a RIP.
Click here for a CMYK PDF file (with black over print still active) ready for printing to RIP, inkjet, or laserprinter.
10% Grey Testing File
To calibrate a printer, it must be a consistent, repeatable device. One way to test this is to print a CMYK file with 10% grey. Examine the print and see if there are any artifacts or banding. Then print the file again. If it looks identical to the first print all is good. Otherwise, if it is extremely different, you probably will not successfully get a usable ICC profile.
