If the accompanying reproductions be examined, this will be found to be the case.
To any one who has given pictorial matters much thought, the disadvantage of this will be at once apparent.
In black-and-white pictures, white is the highest expression of light, and yet how far the whitest paper is from sunlight, and how much shorter the whole gamut of tones, from blackest ink to whitest paper, is when compared with the scale of Nature, have often been pointed out and are now generally understood. But our half-tone process makes the range of tones still shorter by curtailing it at the top of the scale and cutting off the white: the pervading "tint," or "grain," reducing white to a light grey, and not even the deepest blacks and intermediate tones are nicely rendered except by very careful printing. The printing of half-tone process blocks has received great attention amongst better-class printers of late, with the result that marked improvement has taken place, and it is clearly seen that be a half-tone block ever so well made it is only admirable when special ink and special paper (notably a fine clay surface paper) are used, and more than ordinary knowledge and care expended in the machining.
While the ideal process block is one in which, when the process is completed, the block is ready for the press (and many process houses pride themselves upon turning out "untouched" blocks), yet there are few houses who do not employ some hands who are constantly working with engraver's tools to "improve" the blocks after the last etching is done.
Much brilliancy of contrast and effect may be accomplished if the engraver cut away the grain altogether on that part of the surface of the block where it should print white; but this must necessarily be done by men of instinctive taste and good judgment, for immediately hand carving be admitted the essential character of an automatic facsimile process is lost. The illustrator or artist will, therefore, unless he give careful and precise instruction as to what parts are to be cut away, or can superintend the work himself, feel considerable hesitation in entrusting such a delicate task to a stranger. One little touch in the wrong place, one bit of plain white too many, and the harmony of the whole illustration will be upset; so that many will reasonably prefer a weak flat print to the uncertainty which must attend the leaving of a block to a mechanic's mercies.
In the accompanying three illustrations we have, first, an untouched "half-tone" block from an ordinary photogram; secondly, a block from the same original, "fine etched" or with the etching controlled so as to brighten the effect; and thirdly, a block made from the same photogram which, in order to compensate for any failings of the process, has been worked on by the artist, strengthening the shadows and brightening the lights.
This brings us to consider the subject of working on photograms by hand, and the preparation of illustrations generally, which is dealt with in a separate chapter.
