Description
Известен способ изготовлени желатиновых форм высокой печати, состо щий в том, что желатиновую пластину очувствл ют в растворе бихромата аммони , после чего пластину просушивают, экспонируют на нее растровый негатив и про вл ют изображение водой. Дл изготовлени форм примен ют желатиновую пластину с подложкой, что затрудн ет и усложн ет процесс и приводит к снижению качества формы. 1ак, например, при очувствлении желатиновой пластины с подложкой, высушивании и про влении происходит коробление и расслаивание подложки.A known method for making gelatin letterpress forms is that the gelatin plate is sensed in an ammonium dichromate solution, after which the plate is dried, a raster negative is exposed to it and the image is shown with water. A gelatin plate with a substrate is used for the manufacture of the molds, which complicates and complicates the process and reduces the quality of the mold. 1a, for example, when sensing a gelatin plate with a substrate, drying and developing, the substrate warps and stratifies.
Предлагаемый способ устран ет эти недостатки и улучшает качество формы, что достигаетс обработкой пластины без предварительного помешени ее на какую-либо подложку .The proposed method eliminates these disadvantages and improves the quality of the form, which is achieved by processing the plate without first placing it on any substrate.
Способ осуществл ют следующим образом.The method is carried out as follows.
Желатиновую пластину толщиной около 250-300 мк очувствл ют в растворе бихромата аммони . После просушивани на пластину экспонируют растровый негатив и про вл ют изображение теплой водой. В результате про влени на пластине образуетс рельеф, с которого производ т печатание на печатных типографских машинах.A gelatin plate with a thickness of about 250-300 microns is sensed in an ammonium dichromate solution. After drying, a raster negative is exposed to the plate and the image is shown with warm water. As a result of the development, a relief is formed on the plate, from which printing is carried out on printing presses.
Готова желатинова форма наклеиваетс на дерев нную колодку стол рным клеем, а на металлическую или иную колодку - при помощи липкой ленты.The finished gelatinous form is glued onto the wooden block with table glue, and onto a metal or other block with adhesive tape.
Предмет изобретени Subject invention
