hp315 printing grays as tan

[Geneva Olson]

Gray consisting of colorbuilds are problematic on Latex printers, if they are not calibrated regularly. As the heads ages they seem to drift quite a but, it is just in the nature of these printers.
Use an external spectrophotometer instead of the build in will also give you a slightly better calibration.

so here's an interesting conundrum. Like I said originally, I printed the same banner 4 years in a row. NOW, the graphic in this banner consists of part of the graphic as a jpg. Suddenly it started printing tan. I pulled the pdf version of the logo and replaced it. Fixed the print, but just curious why it printed consistently for 3 years and then year 4 (two months after a printhead swap) it prints funky. the rest didn't have a printhead swap.

The problem is lack of calibration after a new printhead. Like I said before if the printer will no longer calibrate then you need to get it fixed or use the RIP, external Spectro, Linearize and create a new profile.
