The size is determined by the sheet of stock out of which blotters are cut. As the stock measures 19 × 24 inches, most printers cut blotters a trifle less than 9½ × 4 inches, thus securing twelve blotters to a sheet of stock. There are others who prefer the blotters not so wide and make them 8 or 8½ inches.

Another reason for the blotter size of a trifle less than 9½ × 4 inches is that it fits nicely in a standard No. 10 Government envelop, which measures 9½ × 4⅛ inches.

A size of blotter that is also much used measures about 6 × 3¼, and fits in a No. 6¾ Government envelop, which measures 6½ × 3⅝. This size is most convenient for inclosing with everyday business mail, and it is possible that most of those actually using blotters prefer the smaller size.

The blotter with an enameled surface on one side is probably the best for use. A person naturally rubs his hand over the blotter to absorb the wet ink, and an enameled surface feels more pleasant to the touch. When not many blotters are on hand in a business office those with absorbent surfaces on both sides render the greater service, but usually advertisers keep offices well supplied.

From a printing point of view the blotter stock with one side enamel-finished is better for illustrations or small type, while rough-finished stock is suited to typographic treatments that require antique effects.

Example [356] (Insert).—This blotter represents not only the size of a great many blotters but the contents, as it is customary to include a monthly calendar. Too frequently forms of this character are made inharmonious because stock calendar plates are utilized and are accompanied by type-faces of another design. This lack of harmony is seldom necessary, as the printer in his typography should match the style of type used for the stock calendar plate. Sometimes in addition to the calendar plate a stock illustration is also introduced, with consequent duplication of spots of attraction. Either the calendar plate or the illustration should be used; not both. The typographic arrangement of blotters oftentimes is of a poor kind because the copy is separated into numerous display parts. In so far as it is possible, the treatment should be simple, and in order to suggest such treatment this example has been prepared. It will be noticed that the entire blotter has been set in one design of type-face—all roman, and mostly lower-case. This manner of handling the typography will give good results in almost every instance in which it is tried. The message of the advertiser is presented in a plain, legible paragraph introduced by an initial in color. The blank space liberally distributed is restful, and the dark-printing qualities of the heavy-and-light-line border contrast with the blank background, the rubricated initial and the mass of gray in the type matter. No rule lines appear in the calendar section, and the result is an appearance of natural freedom.
