WHAT IS DIGITAL PRINTING?
If you are looking for a more modern technique for your printing needs then digital printing should be your choice, as in this method digital files are used instead of printing plates. There are several benefits and advantages of using this technique for printing your itinerary; Personalisation and variable data- Variable Data Printing (VDP) allow for the customisation of individual graphics or text on a print by print basis.
Digital printing is the ideal option for personalised direct mail campaigns because every impression from it can be different. Every kind of business whether small or large can make use of digital printing for printing their literature. In this method, your artwork is created on a computer and then printed directly on the material of your choice. When compared to those traditional methods like lithography, flexography, gravure, and others- a digital printing method eliminates many mechanical steps that are required in other conventional printing, like making films and colour proofs.

HOW DOES IT WORK?
In the digital printing method of production, prints are made from electronic files. In this method, the image is sent directly to the printer using digital files in either PDF, TIFF, PSD, or other formats. Digital printing is mostly used for items that require a high amount of details and smaller quantities. Unlike conventional printing, there are no pre-press stages between the digital document files and the final product; also there is no need for messy formatting equipment such as film plates or photo chemicals. Digital prints should come out great if the following stages of production are done accurately and correctly.

1. The file is prepared with a clean and sharp image in a high enough resolution for the print’s size requirements.
2. Crop marks and bleed are added as needed.

The lines on the corner of the print job are crop marks. After trimming is done the bleed, crop marks to ensure that no unprinted edges should occur in the final document. 3. The next stage is imposition – ensuring that as much of the area of the paper as possible is used for the print to make the job efficient and cut down on paper waste. 4. Before being sent to the printer, your electronic document file (the image or text that you are printing) will need to be converted to a BMP, TIFF, GIF, or JPEG file format. These are known as raster image files or bitmaps.

BENEFITS OF DIGITAL PRINTING-
Speed and quality- if you want a printing technique that is fast but still maintains the quality then digital printing is the best option as Unlike lithographic printing, there is no need to prepare plates so minimal set-up time is required. Also, digital technology has improved significantly over recent years, and at times surpasses traditional offset (lithographic) printing and exceeds competing digital printing technologies. Versatility and value- digital printing is very versatile and can be used at various places, also it can include certified substrates, synthetics, darks and metallic. Since digital printing is so quick and takes up minimal time to be set up, thus, this results in a higher value. Cost-effectiveness and quality- the lithographic technique of printing significant costs mainly occurs in the set-up process, as making the plates and running the spare materials are necessary to ensure that all the inks are in the register before the press can run and because of these the costs get higher. The digital printing technique reproduces the effect of full-colour printing without the need for set-up time and costs, which results in a minimal print run or initial cost incurred before the printing process. LITHOGRAPHIC PRESS VS DIGITAL PRESS, Printing method- Printing with the litho press, the image is first burned onto a plate and then transferred from the plate to a rubber blanket, before being finally printed onto the paper. In digital printing the mechanical steps are eliminated, the image goes straight from the computer, in a pdf form or any other way. Thus, no plates are required, so there is no wastage of ink and paper. Speed- To setup litho printing takes up a lot of time as the design has to be made on printing plates. However, when this process has been done, litho printing produces more prints - around 18,000 per hour. Whereas the digital printing method doesn’t take up much time to set up, all you have to do is upload your design into the computer and press print, just like the everyday office printer. Quick and easy, once the print has started it can print off around 4,800 sheets per hour. Cost- While using the lithographic technique for your printing purposes there is an initial setup process before the printing begins, so there is a setup charge. This means there are no upfront costs when it comes to lithographic printing. Whereas, digital printing doesn’t take any time to set up so there is no initial setup charge; so you don’t have to pay a penny until the printing process begins. Only pay for the paper that is being used and what is known as the “click charge”, which is when each sheet goes through the digital printing machine.
