All you need to know about Digital

What is the difference between digital print and litho print?
With digital printing it is easier to personalise each print as there are no plates required – this offers the advantage of being inexpensive for small print outs.

How are files supplied for printing?
The best way to supply files to print is in a print ready PDF created from a page layout programme e.g. Quark, Illustrator and CorelDraw etc. Word documentscan be used but please be aware that the layout for these files can alter on different computers.

What different types of digital presses are there?
There are Electro-photographic dry toner systems, Electro-photographic liquid ink systems and Ink Jet systems.

Why are digital papers more expensive?
In order to provide the best runnability characteristics required on digital presses include; correct grain direction, no size variation, edge squareness and absence of edge dust.

Does digital printing always limit size of printed matter?
Not necessarily, there is always a choice. The majority of sheet fed colour digital is SRA3 or around SRA3 but presses such as the iGens can go up to 660mm x 364mm and wide format inkjet presses extend both widths and lengths to suit all end uses.

Where do I go for digital finishing equipment?
Although there are specialist digital finishing houses around the UK, both Morgana and Duplo pride themselves in digital finishing kit. More recently the presses have in-line finishing capability.

Are papers in all digital sizes generally available?
Premier Digital prides themselves in supplying digital just-in-time paper requirements. Stocked sheet paper sizes include, all in millimetres; 320×450, 320×460, 320×470, 320×475, 320×482, 330×475, 330×482, 364×521 in the appropriate grain directions. We have rolls for Xeikon and Wide Format Ink-jet printers also.

What if I need a size that you do not stock?
We have a dedicated digital conversion room if there is a size for a specific paper from our range that is required.

What is a script file?
This is a file which lists set of recommended setting per media to prepare  a press for printing on a specific media. Generally these are set by the OEM. Xeikon presses used to produce these in conjunction with paper manufacturers although more recently they do not. Wide Format Ink Jet presses use ICC profiles in the same way.

Should I use only recommended media on my digital press?
Some OEMs only test limited papers prior to launching their presses and only list those to their customers. More often than not there are many alternatives if not the same quality under a different name.

What is ECF?
ECF stands for Elemental Chlorine Free. It is a common definition for pulp bleached without using elemental chlorine. Originally any of the bleaching techniques for chemical pulp, when no molecular (elemental) chlorine is used.

What is TCF?
TCF stands for Totally Chlorine Free. The paper concerned is bleached using hydrogen peroxide instead of chlorine. This is the most environmentally acceptable method of bleaching.
