Computer-to-plate (CTP) technology is used on a daily basis in offset, flexography, and screen-printing workshops. As for pad printing business, computer to plate equipment – laser plate-etching systems – are created only recently. But, with most recent developments, laser-based systems have the potential to master pad printing market over the next couple of years.
CTP benefits: Laser systems enable the user to turn ctp machine price to a highest quality etched impression in only one to five minutes. Costs of movies, chemicals, consumables shipping, exposure units and removal of hazardous substances are eliminated, as are maintenance contracts on processing equipment and prices of outsourcing steel plate making. Double-sided laser etched plates can accommodate up to four images, which reduces plate usage.
You will find four steps to create a plate: import the graphic file into the system ‘s software, apply the halftone style to the image, specify the etch-depth parameter within the laser ‘s operating software, and press start. Laser-imaged graphics are very first generation so there is no loss in resolution.
Etch depth and halftone pattern can be accurately fine-tuned to match the type of image you would like to rheology, the viscosity, and print of the ink for the printer used, the speed of the printing machine, and the durometer of the printing pads used. As specs can be saved on the computer, resulting image quality is totally repeatable.
Laser-based CTP systems are able to accommodate CTP machine parts for fine, combination fine/bold, and bold graphics. Laser-engraved plates have a straight-walled etching and more highly accurate inkwell than polymer cliches and thin or thick steel plates.
Choosing a CTP system: Laser type. These days, three sorts of lasers have actually been utilized to create pad-printing plates: diode-pumped Yttrium Aluminum Garnet (YAG), Ytterbium fiber laser (YAG wavelength), and CO2. The main differences between these products are maintenance, spot size, and power to etch a variety of materials.
Maintenance – The diode-pumped YAG incorporates a diode bar which heats up which enables it to warp after aproximatelly 10,000 hours of use, requiring costly replacement. The Ytterbium fiber and CO2 lasers don’t have diode bar so they have absolutely no maintenance requirements for as much as 70,000 hours of operation. Spot size – Since the wavelength of any YAG laser (1.064 microns) is ten times smaller compared to the CO2 wavelength (10.64 microns), the former has the ability to produce more detailed graphics than CO2. Materials – YAG lasers are ideally suited for metals. A CO2 laser beam is better absorbed by organic substances – wood, textiles, glass, plastics, paper, as well as rubber.
Software. To ensure seamless integration into the workflow of the target business, laser software should have the ability to import are,ai (Adobe Illustrator),,dxf (CorelDRAW, AutoCad), and,bmp (bitmaps, gradients, process-color images) files. to be able to achieve halftone or perhaps dot pattern, the software program must be able to apply many hatches (or separation anhubg the laser lines) on the image. For fine line graphics a small hatch can be applied, for bold graphics a bigger hatch may prevent “scooping”. The energy and frequency of the laser must be adjustable to finely tune the plate level to offer likely the greatest printing plate for the ink type, production speed and substrate. The target degree of etch in the plate is,001″
System features. The ctcp machine have many available features to consider: Size of system footprint – stand by itself or perhaps benchtop system. Vector-tracing software. Micro-adjust focal distance. Plate registration systems. Particulate evacuation systems. Pre-etch laser pointer. Availability of auto-load.
It can look like a little strange that Europe seems to be at the front side of the technology, one normally thinks of Japan or perhaps the Usa for originality but for once legislation could were a help as opposed to a hindrance. Europe has increased it’s expectations of industry meeting environmental needs in a manner that is forcing improvements in your office.
Traditional film making uses chemical compounds that are hazardous in use and difficult to dispose of, perhaps this has improved the demand for earlier film products to improve. Many litho printers (us included) will have used laser plates at once or even another for easy short run one colour jobs, it’s easy and quick, printed directly from the desktop. The issues are damping problems which make these plates tough to run these days it is a possibility to cultivate constructive metal plates using inkjet film. Each and every year the report from DRUPA is the progress the printing industry is making in CTP.
