Again it is extremely difficult to get a clear, clean impression from a rubber stamp. Printing Titles from Zinc-Cuts A far better device is used in many offices, especially for large sets of drawings. The title is carefully lettered at large scale on white drawing paper in black ink. From this, at small cost, a zinc etching or cut is made. This cut or printing block is then inserted in a wooden frame or box with a hinged cover, so that the cover, which has an opening in it a little larger than the cut, when closed down is flush with the printing surface of the block. The tracing is now tacked to the cover, face down, with the title space over the opening, black printing ink is applied to the cut with a regular ink roller, the cover with tracing is closed down and the back of the tracing is rubbed over the inked cut. A clear, clean-cut imprint is the result. This is by far the easiest and best way to title a number of sheets uniformly. Sytems of Numbering The system of numbering is also capable of considerable variation. The simplest thing to do is to number consecutively. It is better, however, to separate the drawings into classes, which allows for insertion of drawings without breaking the chain of numbers and also serves as an index to the character of the drawing. The following table will illustrate the point: 1--99, General Drawings 100--199, Scale Details 200--upward, Full size details or a more elaborate subdivision for very large sets: 1--99, General floor plans 100--199, General sectional drawings 200--299, General elevations 300--399, Scale details, exterior 400--499, Scale details, interior 500--599, Full size details, exterior 600--699,...
