Fig. 21.—Manner of holding the paper.

Particular attention must be given to the careful placing of the paper home in the register notches, and to holding it there until the rubber has gripped the paper on the block.

Sheet by sheet all the printing paper is passed in this way over the key-block, and piled together. There is no fear of the ink offsetting or marking the print placed above it. As the work proceeds the block will give better and better impressions. Spoiled or defective impressions should be put together at the top of the pile when it lies ready for the next printing, for the first few impressions are always uncertain, and it is well to use the defective prints as pioneers, so as not to spoil good ones.
