The power and frequency of the laser must be variable to finely tune the plate depth to provide the best printing plate for the type of ink, production speed and substrate.064 microns) is ten times smaller than the CO2 wavelength (10. As specifications can be stored on the computer, resulting image quality is completely repeatable. Laser-imaged graphics are first generation so there is no loss of resolution. System features The CTP systems have several available features to consider:
Size of system footprint stand alone or benchtop system Vector-tracing software Micro-adjust focal distance Plate registration systems Particulate evacuation systems Pre-etch laser pointer Availability of auto-load Availability of future expansion For more information please visit . 2. The Ytterbium fiber and CO2 lasers have no diode bar so they have no maintenance requirements for up to 70,000 hours of operation. However, with latest developments, laser-based systems have the potential to conquer pad printing market over the next couple of years. A CO2 laser binding wire manufacturers beam is better absorbed by organic materials wood, paper, plastics, glass, textiles, and rubber.
Laser-engraved plates have a straight-walled etching and more precise inkwell than polymer cliches and thin or thick steel plates. Laser type Today, three types of lasers have been used to make pad-printing plates: diode-pumped Yttrium Aluminum Garnet (YAG), Ytterbium fiber laser (YAG wavelength), and CO2.001" 3. Spot size As the wavelength of a YAG laser (1. As for pad printing industry, computer to plate equipment laser plate-etching systems have been introduced only recently. Costs of films, chemicals, consumables shipping, exposure units and removal of hazardous materials are eliminated, as are maintenance contracts on processing equipment and costs of outsourcing steel plate making.
Laser-based CTP systems can accommodate operating settings for fine, combination fine/bold, and bold graphics. Materials YAG lasers are ideally suited for metals.64 microns), the former is able to produce more detailed graphics than CO2. For fine line graphics a small hatch can be applied, for bold graphics a larger hatch will prevent "scooping". In addition, CTP users enjoy a number of cost-saving benefits: double-sided laser-etched plates can accommodate up to four images, which reduces plate usage; Choosing a CTP system 1. Maintenance The diode-pumped YAG has a diode bar that heats up and can warp after about 10,000 hours of use, requiring costly replacement. Etch depth and halftone pattern can be accurately fine-tuned to match the type of image you want to print, the viscosity and rheology of the ink used, the speed of the printing machine, and the durometer of the printing pads used.Computer-to-plate (CTP) technology is used on a daily basis in offset, flexography, and screen-printing workshops.bmp (bitmaps, gradients, process-color images) files.
