Usually, stickers are printed on a special web label printer. However, due to the unique structure of multiple small offset presses, we used a variety of small offset presses to print stickers and achieved good results. Our experience is summarized below for your reference. 1 Do not print directl

Amoco used the clear agent Millad 3988 to produce the Acclear series of highly transparent PP by gas phase process. The base resin of this product is usually random copolymer PP. Among them, Acceptar 8649X [MFR 23g/(10min)] PP is suitable for injection-pull-blow moulding bottles with a transparenc

In general, there are three main factors that determine the quality of the print version of a PS plate: the quality of the plate, the exposure time, and the quality of the development. Correctly and reasonably grasping the exposure time is a crucial step to ensure the quality of printing. Correctl

One, lithographic ink and water balance We all know that lithography is based on the basic principle of immiscible oil and water (except waterless offset printing), in which the blank part first adsorbs water to resist the ink. Then, the image part is adsorbed by ink to form lithographic printing

The CIELAB color space is a set of descriptive color data that the International Illumination Association converts the wavelength of light into luminance and hue according to the characteristics of human vision, where L describes the brightness of the color, A describes the color from green to red

The PANTONE color standard certification of the United States is a unified description of colors in a digital language. It provides a convenient and fast color scheme and color standard for the packaging and printing industries and ink manufacturing industry. In the developed countries of the ink

Water-based inks are mainly composed of hydrophilic acrylic resins, pigments, water and additives. In the conventional alkaline deinking process, hydrophilic acrylic resins cause great difficulty in deinking waste paper. The main reason is that The ink particles peeled off from the fibers in the p

Spot-color platemaking is the production of only one type of color plate at the time of plate making, without the need for multi-color overprinting, the use of spot color inks for printing, or printing of special colors by ink transfer. Spot colors are mostly on-site density, and there are fewer m

Printing glazing machines are divided into glazing machines (including calenders) and printing glazing machines. Domestic polishing machine is generally a stand-alone operation, the processing speed is slow, the quality is not high, for this reason, it is often necessary to re-calender processing.

In the offset printing process, especially the single-color offset printing press, regardless of Y, M, C, BK four-color printing, trademark, packaging and decoration often need to wash the ink to change color, the entire offset printing machine's ink system is cleaned, and then Put on new ink.

First, the classification of the lining Offset printing plate cylinder and blanket cylinder (rubber roller) surface lining, blanket cylinder roller lining can generally be divided into the following three categories. 1, hard pack liner Generally, a few sheets of paper under the blanket constitu

Although the use of flexible plates in corrugated boxes started later in the country, there are many advantages in flexographic printing, including the decreasing price of flexographic plates, fast platemaking speed, fast drying of ink, good printing performance, and small damage to corrugated car
