One challenge that companies new to inkjet face is to move customers from a model where they control paper buying to one where they are expected to choose from a list of approved papers. Another challenge is to get customers to send files that are designed appropriately for the paper selected and the device it will be produced on. One tool that can help with both of these challenges is what is known as a fingerprint file. You may be familiar with the concept of fingerprinting a print device. In that scenario, a test file composed of variations of different “visual hurdles” is used to measure production quality on the printer, usually before buying the printer. A fingerprint file designed for your customer will help them to understand how your inkjet printer handles the visual hurdles that designers will throw at it – and how that performance may differ on specific papers, or under certain production parameters that you control. The fingerprint is about setting expectations:
  • What can they expect on each paper you offer?
  • How do results differ from your standard performance mode to high-quality mode if available?
  • Will images look very different if saved in 300 dpi instead of 600 dpi?
To set expectations properly, create an attractive visual that includes sections to help the customer see how the printer handles different text sizes in positive and reverse, various line weights, halftones, solids, color fidelity and show through. It should include areas of low, medium and high coverage as well as vignettes. Attached are fingerprint examples with images in 300 dpi and 600 dpi that you are free to use. Tip: Run a few copies of your fingerprint at the end of jobs on each type of paper you use so that your sales people have plenty of samples. However, since colors can fade over time, include the date printed on each sample and discard old samples when appropriate. Remember to include the name of the paper and information like optional resolution or speed settings used to avoid confusion. Note: these suggestions assume that you have already completed Print Quality Analysis with your selected papers and calibrated your printer. You want to be sure that you are not offering customers options that will curl, cockle, mottle or have issues with two-sidedness in production. In addition, make sure that you are not experiencing any jet-outs or cross-process density issues before creating and distributing fingerprint samples.
