RETOUCH, RE-SET, RE-ENGRAVED, RE-DRAWN, RE-CUT.--All these terms have a somewhat similar meaning, and imply repairs to, or alterations of, the die, plates, stones, or blocks: instances of most drastic re-engraving are known, _e.g._, that of the 1848 Two Pence ("Post Paid") of Mauritius, the plate of which was so altered as to produce a practically new stamp, the Two Pence, "large fillet," of 1859; and the Half Tornese "Arms" of Naples, which had the entire centre removed from each of the two hundred impressions on the plate and replaced by the Cross of Savoy. To differentiate--_retouching_ is generally undertaken to remedy minor defects caused by wear and tear: _re-setting_ suggests slight re-arrangement of stamps made up, wholly or partly, of printer's type; _re-engraving_, the replacing of parts of a design worn away by use or intention: _re-drawing_ rather leads one to infer that the original design has been reproduced in an improved form; and _re-cutting_ implies going over the original die, &c., and strengthening the engraving, with, perhaps, slight accidental variations of the design. REVENUE.--This word indicates availability for fiscal use, as distinguished from postal use. A stamp may be available for either purpose, or for one only; the use is almost invariably indicated by the inscription. REVERSED.--Backwards-way; "as in a looking-glass." The term is often, but quite erroneously, used for INVERTED--which see--implying upside-down. RIBBED.--_See_ PAPER. ROSACE.--The small ornament frequently found on the upper flap of old envelopes; known also as TRESSE. ROUGH PERFORATION.--When the holes in the lower plate of the perforating-machine get damaged or partly clogged up, or the punches are very worn, the perforation becomes very defective, the little discs of paper not being punched out, but (though generally distinct) left only partly cut through: this state is termed "rough," but must not be confused with PERCÉ EN POINTS (pin-perforated), which see. ROULETTED.--_See_ PERCÉ. ROULETTED IN COLOURED LINES is a variety of rouletting, and always so termed, in which the slits or cuts are made by means of type ("printer's rule") a little higher than the CLICHÉS or STEREOS composing the plate, and which cut into the paper under the pressure of the printing-press. SAFETY PAPER.--_See_ PAPER. "SEEBECKS."--The late Mr. N. F. Seebeck, the contractor to various South American Republics had an arrangement under which there was a new issue of stamps every year, he to retain for his own benefit any demonetised remainders of the previous set: stamps provided under such conditions are called after their originator.
