The black order

[efingo]

I just saw an order from a company to another for some stuff to buy.
The order is black printed with white text.
How is this done? I can't imagine inserting black paper in a printer that print text with white.
Any ideas?

yes that is not digital printing, but really press!
For so far i know, there are to ways to do this:


1) serigraphy
2) pantone collors

So what, they do serigraphy each time they issue an order?

Thank you for reply

I believe they would screen-print it on which a white ink. At least, thats how i've seen jobs done on black/dark stock...

or the use a press with pantone collors..
tis is possible, but the more collors u use then, the more you pay....

this is one option:(spot collors)

A spot color is a specially mixed ink that is applied on the printing press, as opposed to a mix of the four inks which make up process printing. Spot colors can be produced in a much more vibrant range of colors, and can have special characteristics which aren't available in process inks, such as day-glow or metallic ink.
Because they only use one ink roller, one plate, and one negative, spot colors can reduce the cost of printing if you limit your ink choices to black and one spot color. For example, if you choose to print a red and black letterhead in process inks, you will actually need three inks on three rollers (with associated plates, etc): Magenta, Yellow, and Black.
However, if you are already printing a full-color piece, adding a spot color will dramatically increase the cost of printing. You will add one more color to the four colors needed to produce, for example color photographs. It then is a five-color job requiring five inks, five rollers, five negatives, five plates, etc.
Many companies make spot colors, but the most popular is Pantone, Inc. They not only make and sell inks, but they have a process which enables printers to mix the exact same colors from a set of base inks.

you're right cre8, you could do it that way. but I don't know how much white works in that way other than screen printing - we need a printer to answer this one...

They do the same thing with The Yellow Pages Phone Book (here in the U.S.). If you can get your hands on one, they actually print white on yellow paper.

Same with the yellow pages in the the UK.
