Offset printing is an established, popular printing process where the inked graphic image is transferred directly from a thick plate to a solid rubber substrate and then onto the printing surface. When employed alone, the offset method uses a flat plate carrier, but when used in combination with the digital print process, which involves the binding of the graphic image directly to the carrier material, the offset method uses a die-cut, heat-sensitive cutting unit. what is offset printing , and the major benefit to using the offset method, is the ease with which large volumes of printing can be completed, as well as the speed with which it delivers prints. This is because all the work that is involved in preparing the printing surface, preparing the ink for the print and transferring the image, is carried out before the client actually receives the print itself.
Because of the high cost involved in digital printing, there are times when businesses may prefer to use offset printing in order to reduce their overall costs. However, there are limits to this approach, particularly when the print job requires colors or when the intended final color scheme does not match the final Pantone shade. If these factors are ignored, the result may be poor color quality, even when the colors are closely matched. For instance, if the Pantone shade for a particular print is #ffcc00, but the intended print comes out as purple, this may not be a good result. This is because the Pantone color would be too light and it will not be appealing to most users. This problem can be addressed by using a different offset printer, or by printing digitally.
Another advantage that offset printing offers is the fact that it produces a higher level of quality as compared to digital printing. In this method, the printouts remain consistent, even during the processing stage. The printer, therefore, does not have to pause before processing in order to re-create the image needed for a new print. In most cases, the process simply makes use of the already printed data. The variable data printing used by most offset presses usually allows you to choose the final output format, such as PDF or TIFF, as well as the color mode.
In most cases, offset printing also uses a fixed data feed through which the printed images are fed. The feed moves continuously through the printer head so that each successive image gets placed on the appropriate plate. As the name suggests, this unit is usually mounted on the print tray, where the image stays until it is finished.
While some small companies cannot afford long distance printing, they do not have to worry about short runs either. In this case, there is another option that you may consider. It is called digital printing or offset printing coupled with screen printing. Digital printing involves the use of a computer-generated print command. Unlike traditional offset printing, the unit cost for digital printing is significantly lower.
It works like this. You choose the image or graphic and then supply the design as an electronic file to be printed. The unit reads the file, places it on the appropriate print tray and then does the printing. The print quality is top notch when compared to offset lithography and other forms of commercial printing. With today’s digital printing technology, you have nothing to lose when you switch to digital printing for your printing needs.
