Digital printing guidelines
Digital Printing describes the process of transferring a document on a persm onal computer or other
digital storage device to a printing substrate by means of a device that accepts text and graphic output.
As with other digital processes, information is reduced to binary code, or "digitized," to facilitate its
storage and reproduction. Digital printing has steadily replaced lithography in many
markets, especially at the consumer and business level, as a result of its substantially
lower production costs.
Many modern printing methods are used nowadays, such as laser and ink-jet printing are known as
digital printing. In digital printing, an image is sent directly to the printer using digital files such as PDFs
and those from graphics software such as Illustrator and InDesign. This eliminates the need for a printing
plate, which is used in offset printing, which can save money and time.
Without the need to create a plate, digital printing has brought about fast turnaround times and printing
on demand. Instead of having to print large, pre-determined runs, requests can be made for as little as
one print. While offset printing still often results in slightly
better quality prints, digital methods are being worked on
at a fast rate to improve quality and lower costs.
When preparing a document to send to a printer, there are several specifications and elements to
include in your layout. These specs help to insure that the printer will provide your final project as
intended. Information on trim marks, trimmed page size, bleed, and margin or safety are included in this
article on preparing your document for the digital printing process.
And when it comes to color separation, you should know what is this
process. it is the process by which original artwork is separated into
individual color components for printing. The components are cyan,
magenta, yellow and black, known as CMYK. By combining these colors, a
wide spectrum of colors can be produced on the printed page. In this
four color printing process, each color is applied to a printing plate. When
the colors are combined on paper (they are actually printed as small dots),
the human eye combines the colors to see the final image. The use of
plates for printing is part of the process known as lithography.
Sending Files to Your Service Bureau
When you send a digital file out for film or printing more goes
along than just your PageMaker or QuarkXPress document. You
may need to send fonts and graphics too. Requirements differ
from one printer to another depending on their printing process
but if you know the basics for sending files to your service bureau
(SB) or printer it will elminate most common problems that might
prevent them from processing your job.
Tips for Digital Printing
There are several things to keep in mind when designing specifically for digital printing.
Color: A digital press uses toner, not ink. Colors render differently on a digital
press vs. an offset press. While the quality of digital presses has come a long
way, you will be able to tell a difference. Also note, when using PMS or
Pantone colors, these colors will be printed as a build of CMYK. It is important
to watch large areas of heavy ink coverage, banding or blending issues can
Paper: Digital presses can sometimes require use of specific papers that are
compatible. Other presses such as the Kodak Nexpress do not require such
papers. You can use the same stocks as an offset press. Be sure to check with
your printer before choosing paper stock.
Finishing: Think finishing at the beginning of the design process. The more you understand about how
the finished product will be produced, the better. For example, since toner does not sink into paper like
ink, heavy coverage can cause cracking along folds. With this in mind, you can design the piece to have
less coverage where it is going to be scored/folded.
Bleeds/Margins: Digital printing requires more tolerance for registration. This means you must supply at
least an 1/8 in bleed for any image area reach the edge of page. This will ensure that your design is not
cutoff in the finishing process.
Image resolution: Digital presses require a minimum of 300 dpi resolution to guarantee high quality
photo production. Do not use photo files in a compressed format like a jpeg. When possible use a source
format like .eps, .tiff or .psd. And try not to enlarge photos from their original size.
Text legibility: Avoid using font sizes smaller than 4 pt. For greater legibility, keep to high contrast
colors and uncomplicated fonts.
