A rotogravure illustration when looked at through a small magnifying glass appears as many small squares, less clearly than a halftone.

Right Way to Make Crop Marks.

Put crop marks in the margin of a photograph or drawing. If you MUST mark the copy, use a China marking pencil for this purpose. The reason for this is simple:-- crop marks drawn on the photograph oblige the engraver to make the plate smaller than the size indicated by them.
