Other Methods of Printing

其他印染方式

Although most work is executed throughout by one or other of the five distinct processes mentioned above, combinations of them are not infrequently employed. Sometimes a pattern is printed partly by machine and partly by block；and sometimes a cylindrical¹ blockis used along with engraved² copper-rollers in the ordinary printing machine. The block in this latter case is in all respects, except that of shape, instead with a flat wood or coppered block, but, instead of being dipped in color, it receives its supply from an endless blanket, one part of which works in contact with color- furnishing rollers and the other part with the cylindrical block. This block is known as a surface or peg³ roller. Many attempts have been made to print multicolor patterns with surface rollers alone，but hitherto with little success, owing to their irregularity in action and to the difficulty of preventing them from warping⁴. These defects are not present in the printing of linoleum⁶ in which opaque⁷ oil colors are used，colors that neither sink into the body of the hard linoleum nor tend to warp⁵ the roller.

尽管大多数印染是由上面提到的五个不同的流程中的一个或几个进行，但它们的组合并不罕见。有时打印图案部分由机器进行和部分由木板印染;有时一个圆形印刷是与刻印在普通的印花机一起使用。在后面那种情况下该铜块不是在所有方面和所有不同的是形状，而是在代替平坦木材或镀铜块方面，但是，这不是被浸渍在颜色中，它从无端毛毯接收其供应，其中一个印染颜色的零件与布接触，另一部分与圆柱块接触。这被称为表面或深入印染。进行了与表面进行单独打印多色的图案的许多尝试，但迄今收效甚微，由于其在行动，防止翘曲不均难度很大。这些缺陷不存在于油毡打印，其中使用不透明的油颜色，沉入硬油毡的物体也不容易翘曲。
