Jon Cone’s Inkjet Mall recently introduced Firefly Invisible Ink, an inkiest designed for viewing prints under black light only.

“Firefly™ ink is a sophisticated encapsulated dye ink that is invisible in ordinary daylight. Turn off the lights and expose with a black light and the color is vibrant and life-like. We make Firefly inks in cyan, lt cyan, magenta, lt magenta, yellow and white. Because the inks are invisible and require UV light in order to be seen, images must be printed in a false color in order to appear normal under black light. We produced Firefly™ ink Image Converter software so you do not need to experiment. You can open an image, convert it and save it as jpg or png file to print in any software of your choosing. We also put in some expert tools for those who wish to experiment.”

Kudos for innovation.
All bets are off on longevity.

Ink Drips or Smears

January 25, 2010 | Leave a Comment |

My Fine Art Digital Printing DVD offers many simple solutions to common problems. Here’s one …


I’m getting spots or streaks of ink on my print(s).

Clean the print heads, the rollers, and the inside of the printer.

Sometimes excess ink accumulates from previous printing sessions and gets smeared on the next print. This usually only happens when previous print errors have printed off the paper causing problems for the next print, even if it’s printed correctly.

Sediment in ink can settle so agitating ink that’s been stationary (for more than a month or three) makes sense. Agitate gently, or you may damage the needle valve in the cartridge. You don’t need to do this for ink in a printer, unless you don’t use the printer for a long time. The printers gently rock during use, which provides automatic agitation.

Printing at 2880 and 1440 resolutions uses about the same amount of ink. The difference is 2880 only uses the finest dot (3.5 picoliter) rather than a variable dot structure. (2880 may look a little darker, particularly on matte papers, because the dots tend to bleed together. Use 1440 if you get excessive dot gain – pooling in shadows, spattering in highlights.)

Ink cartridges first have to prime the printer tubes on initial installation. They have to purge shipping fluid designed to prevent clogging during storage. This doesn’t waste ink you paid for. Neither does the ink left in the cartridge when it runs out. There’s actually more ink in the cartridges than listed on the label.
