[title] Test the printer
-[* icon_caution] ***All ink cartridges must have ink left. If all else fails, add ink with a*** ''***DYE OR PIGMENT BASE refill kit (Check what your printer uses; getting this wrong leads to binding and permanent damage). Add ink to ANY low cartridge(s).***'' ***FAILURE TO DO THIS MAY DAMAGE YOUR PRINTHEAD AND TOTAL OUT YOUR PRINTER.***
-[* icon_note] If you have a 5-color "photo" printer (C/M/Y/K/PK), print a photo from your phone or camera if you print photos regularly or run the SMPTE bar test as a photo.
+[* icon_caution] ***Authors' Note: When referring to "beyond CMYK+PK", I am referring to color sets such as CMYK+PK+GR, CMYK+PK+GR+Gloss Optimizer, CMYK+PK+GR+OR+Gloss Optimizer to name a few "common" combinations I have seen.***
+[* icon_caution] ***For printers with colors beyond CMYK+PK, a more advanced test sheet that fully tests the printhead on these models is REQUIRED.*** ++***I am not providing this. Consider using a reference photo set commonly used by photo labs or a photo you have taken personally on a high-end camera like the Sony Alpha series to test your printer.***++
+[* icon_caution] ***All ink cartridges must have ink left. If all else fails, add ink with a*** ''***DYE OR PIGMENT BASE refill kit (Check your printer specs; getting this wrong leads to binding and permanent damage). Add ink to ANY low cartridge(s).***'' ***FAILURE TO DO THIS MAY DAMAGE YOUR PRINTHEAD AND TOTAL OUT YOUR PRINTER.***
+[* icon_reminder] If you have a photo printer such as a 5-color model (CMYK+PK), print the test image as a photo program such as Photoshop, Photos (Mac) (or your preferred image viewer), forcing it to print in photo mode.
[* black] After replacing the printhead, test the printer. Match the previous settings and check for improvement.
