All printers will vary in colour and output between individual devices, even when they are identical printers, inks and substrates.
In cielab’s testing across identical Roland printers we have been surprised at just how substantial the colour difference is. Our testing was comprehensive and included 4x SJ740 printers and 2x SJ-745 printers, all with identical inks and print media, but with printheads of varying ages. We found that in most cases spectral calibration with external equipment did bring this into line, but it does show that generic ICC profile and media settings provided by vendors (not generated in your office with your printer and then calibrated into the other printers) will only get you so far. This is better than nothing however it’s unlikely that you will see consistent results unless you calibrate each individual printer onsite with high quality external measurement spectral equipment.
