    Abstract: Ablation-type printing plates having increased shelf-life are produced using a melamine resin free of water prior to use. A representative production sequence includes providing a substrate having an oleophilic surface; coating, over the substrate, an oleophilic resin composition having (A) a resin phase consisting essentially of a melamine resin substantially free of water and a resole resin, the resole resin being present in an amount ranging from 0% to 28% by weight of dry film, (B) a near-IR absorber dispersed within the resin phase, and (C) a sulfonic acid catalyst dispersed within the resin phase and being present in an amount ranging from 0.7% to 1.6% by weight of dry film; curing the resin composition to produce a dry film; following resin curing, coating an oleophobic polymer composition over the cured resin composition; and curing the oleophobic polymer composition.

    Abstract: A novel ink formulation, especially useful in Driography printing, is disclosed. The ink formulation comprises a basic planographic printing ink vehicle, a pigment, a modifying varnish and a flow control agent to provide an ink, especially suitable for use in Driography, which exhibits desirable hangling-viscosities under ambient conditions, improved rheological properties under severe press-operating conditions, and provides printings having sharp delineation, fidelity and excellent reproducibility in depth of color tones in long press runs. The basic printing ink vehicle may be a vehicle designed for either sheet-fed or heat-set printing systems. The novel ink formulation is designed to have a high viscosity and avoid becoming pseudoplastic in its behavior at higher press temperatures, which generally can range from about 85.degree. F. to 125.degree. F., and preferably, avoids becoming pseudoplastic at temperatures up to about 140.degree. F. or more.

    Abstract translation: 公开了一种新颖的油墨配方，特别适用于Drigraphy印刷。 油墨配方包括基本平版印刷油墨载体，颜料，改性清漆和流动控制剂，以提供特别适用于Drigraphy的油墨，其在环境条件下显示出期望的悬浮粘度，在严格压制下改善的流变性 并且提供在长按压中具有清晰划分，保真度和优异的色调深度重现性的印刷。 基本的印刷油墨载体可以是为单张纸或热定型印刷系统设计的车辆。 新颖的油墨配方被设计成具有高粘度并且避免在较高的压力温度下在其行为中变成假塑性，其通常可以在约85°F至125°F的范围内，并且优选地避免在温度高达约 140°F以上。

    Abstract: Presensitized planographic printing plate for use in dry planography. A positive acting plate having a flexible base and a relatively thick (0.02 to 2.00 mil) silicone rubber layer, overlying a photo-polymerizable and photoadhesive-layer. Upon exposure to light through a positive transparency, the photoadhesive layer in the exposed non-image area polymerizes and adheres firmly to the thick silicone rubber overlayer, but the photoadhesive layer in the unexposed image area remains nonadhesive to the silicone overlayer. Following the exposure, the surface of the plate is treated with developing liquid capable of swelling silicone rubber. The thick silicone rubber layer in the unexposed image area is easily removed, exposing a sharp image of oleophilic photoadhesive layer underlying the removed silicone layer, while the silicone rubber layer in the exposed background area remains bound to the photoadhesive underlayer. The exposed surface of the photoadhesive layer accepts ink from inking rollers, while the silicone rubber background area does not remove ink from the rollers, and thus remains ink-free.

    Abstract: A method of non-overlap halftone-dot printing of a colored original on the outer surface of a cylindrical container is done by dry off-set printing. A colored original is color-separated into three primary colors, i.e., cyan, magenta and yellow, change-to-halftone is effected to give an effect of contact screening with the same angle for the individual separated primary colors, and one pixel of print is expressed by three colors at most, i.e., one of the three primary colors, one of three secondary colors, i.e., cyan-magenta, magenta-yellow and yellow-cyan blend colors, and black (tertiary color).
