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 repeating pattern usually states its own colours, so a hatch in five colours is five patterns in the file. A pattern built without colour states none: it says only what shape repeats, and the colour comes from the fill that uses it.
The page lays one such pattern down in five colours and in five strengths of a single press ink, then shows the ordinary kind beside it so the cost is visible: one against five. On a hatched engineering drawing or a map filled with flat tints, that difference is the size of the file.

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.
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.
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.
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 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 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.
