by default printers assume you're printing on white paper. I have to print on transparent media which doesn't contain the white pigment so I must somehow tell the printer or software to actualy spray white ink on it.

has anybody got a clue on how to solve my problem? I will be mainly printing from photoshop through an Hp psc 1210 BJT printer, if that helps!


peace!

Are you serious???

You don't need white ink (printers don't have it anyway)!

A transparent area on a sheet will be perfectly displayed white on a screen since you're using a white light projector...

isn't white =red+green+blue? therefore it should very possible to print white ink

and what projector are you talking about? this transparent sheet that i will be printing on will be glued onto a black,plastic surface

red+green+blue LIGHT makes white light, but not with ink.

Just put a piece of white paper behind the transparent sheet before you put it up.

Have you actually tried printing to see what happens?

for example a big blue square with a white circle in it?

i thought the printer would understand automatically.??

Unless somethign has changed, bubble jets dont work well on transparencies. You need a laser printer for that.

That would be true, IF printers printed in RGB. The problem here is that RGB is a televisions/monitors represention of color, where black is the absense of all color:

RGB Black
RED = 0
GREEN = 0
BLUE = 0

And white is the colors at maximum intensity.
RGB White
Red = 255
Green = 255
Blue = 255


However, printers use CMYK color to print, not RGB. In CMYK, the color white is represeneted as the absence of all colors:

CMYK white
Cyan = 0
Magenta = 0
Yellow = 0
Black = 0

With that being said, you can see why you can't print white with standard offset (CMYK) printing. The only way to print white is with a screen printer which = expensive.

Most Inkjets don't print to transparencies as standard, you usually have to buy a transparency adapter (which costs about the same as the printer sometimes).

You can buy special Inkjet printable transparencies from some places though.
