Wholesale sales of high quality Huaguang PS version of the series plates ■ exposure (copy) copy source: iodine home for the most suitable light source lamp: Due to the different light sources, plate exposure time will vary, the table is only recommended amount of exposure for a range; when using the same version of its exposure time than normal exposure time by 20%, the proposal to update the lamp. Film: To ensure the quality copy, copy used in the film is recommended density of 3.5 or more. Exposure time: Award STOUFFER21 grayscale foot ladder (differential .015) or UGRA PCW82 control strips in the plate edge, the film below, proper exposure and recommended conditions for development. With gray wedge on the third level of ink when the exposure is not as positive plates optimum amount of exposure to the ninth grade when the ink is not on the amount of exposure to the exposure of the negative plates; or when 10-15μm control bar When the micro-line uninterruptible positive image with candle prevail, Yin Yin figure to the exposure, whichever is the best exposure. ■ developing the developer: Use Huaguang PO type developer (positive plates used) and Huaguang ND-II-type developer (negative plates used). Developer preparation: the male view of a developing concentrated solution volume: the volume of water = 1: 6∽1: 8 Negative developing, the volume of concentrate: water volume = 1; 2. Developing stable: 23 ℃ ± 2 ℃ temperature is too high plate outlets reducing variation, while resulting in reduced anti-Indian forces; the temperature is too low, insufficient capacity development. Development time: the development time of less than 1 minute. ■ Revised edition positive plates using Huaguang PI-type image scavenger. Negative plates using NI want Huaguang video scavenger. After development to eliminate excess water on the plate image, may want to eliminate the parts with a small amount of image scavenger, and make it a period not more than 45 seconds, then rinse thoroughly with water, do not stay too long or rinse thoroughly easily cause the dirty. ■ developing glue, after washing evenly coated with a thin layer of the layout need protection glue. Protection of plastic protective colloid concentration and dosage recommended by the manufacturer shall use, concentration, or excessive use will adversely affect the plate. ■ baked version of baked version of plastic: plastic version should be of high quality baked baked version Time: 5∽10 minutes Baking temperature: 220∽420 ℃ baked version should be strictly the recommended temperature and time of the operation, the time is too short, too low temperatures reach roast Version effect; time is too long, the temperature is too high will seriously affect the performance sheet, especially not only to determine the degree of discoloration plate baked version end. ■ storage, unsealed light, heat, easy to make the coating chemical changes, the recommended storage conditions for 10∽30 ℃, relative humidity less than 65%. Unpacking should be carried out under yellow light; among the recommendations should be shielded plate natural light. In addition to copy other light sources should be yellow. When handling the plate gently to prevent the collision, break, fall, stacking height is preferably not higher than 1.5 meters. ■ ensure the preservation of the recommended storage conditions, positive plates to ensure that 18-month period, negative plates guarantee period of 12 months. ■ Perform standard positive PS plate HG / T2694-95 Negative PS version HG / 2171-91 Company: Dongguan Tianyu Printing Equipment Co., Ltd.

And Micro Piezo technology. Thermal inkjet printer is heated instantaneously by giving the thermistor, the ink droplets emitted boring in the expander to blasting, so that the ink is emitted. Due to changes in the chemical composition of the ink occurs at high temperatures, the stability of the color produced is relatively poor. In addition, this type of print head is a wearing parts, so there is a print quality improvement by changing process bad, devices using this technology would like to keep the color stability is very difficult. Micro Piezo inkjet printing technology is the use of voltage change to make ink from the nozzle exit, it is a solid piece of the nozzle, thus from the root
