Several plates at once, each at a strength of its own

Eight choices of plate among the four usual inks, each with the small program that shows it printed underneath, and two inks the press carries itself used together, every strength of one against every strength of the other.

A DeviceN space names several inks at once, and a colour in it is one strength per ink. Naming some of the four usual plates and not the others is how a document lays ink on those and leaves the rest exactly as they stand; naming inks of its own is how a press that carries more than four gets painted in.

The page shows eight choices of plate among the four usual inks, each with the small program that shows it printed underneath, and then two of the press's own inks used together, every strength of one against the other. If you are producing work for a press rather than for a screen, this is the space that does it.

What this example shows

  • Several named inks painted at once, one strength each.
  • The conversion recipe printed under what it shows.
  • Choices among the usual inks, and inks the press carries itself, both shown.

Examples near this one

Grey, screen and printing colours

Swatches in each of the three ways to say a colour — a grey as one number, a screen colour as three, a printing colour as four inks — each captioned with the instruction actually written into the file, and one mid-grey said three ways.

Colour the document defines

The same six colours said as bare numbers and then read through the sRGB profile the file carries, plus a ramp from light to dark and a sweep of hues in CIE L*a*b*: colour that still means the same thing on another screen and on a press.

Inks on plates of their own

Two inks the press carries on a plate of their own, each at ten strengths, a piece of work set in both, and the crosses used to line the plates up — drawn in an ink every plate answers to.

A chart of colours, and a drawing that names places in it

A chart of house colours the file carries, and a drawing whose sixteen numbers are places in that chart rather than colours. The same drawing is shown twice through two charts: repainting a whole brand is one table, not every drawing.

One hatch, laid down in as many colours as the page asks for

One pattern that states no colour of its own, laid down in five colours and in five strengths of one press ink: the fill says what colour to lay it down in. Beside them, the same hatch made of patterns that carry their own colours, which is one pattern per colour.

A sheet as it goes to the press

One drawing on three pages: a press sheet stating where the ink runs, where the blade falls and what is worth keeping, with corner marks; the same sheet cropped to the finished page; and a landscape page that states a quarter turn clockwise on an upright sheet.

Glossary

CMYK
The four inks a printing press lays down: cyan, magenta, yellow and black. A screen mixes light instead, so a document going to a press states its colours in inks, not in screen colours.
