Cyan, Magenta, Yellow, and Black. In full-colour process
printing, CMYK is the standard method for offset printing. CMYK
colours are measured by their subtractive/reflective values; when the
coloured ink is applied to paper, the surface of the paper reflects
some colour and the non-reflective (that is, absorbent) colour is seen. more »
RGB: Red, Green and Blue. These three colours are projections of light
that can be overlapped in millions of colour-strengths and
combinations to create on-screen colours and images. RGB colours are
associated with television screens and computer monitors, but is not
used in offset printing. more »
RGB & CMYK: The RGB colour process and the
CMYK colour process work in opposite ways. An RGB colour scheme forms
colour through an additive process; to obtain white, all 3 colours are
added together, and to obtain black, all 3 colours are removed. In
contrast, the CMYK printing process obtains white by omitting all
colour, and obtains black by using all four colours. more »
Full Bleed: A small amount of size added to all four sides of a file
to ensure the background is printed and cut to fill up the entire
card as opposed to seeing a white thin line going around the edge of
the card. Usually the added file size is either 1,61mm or 3,175mm.
Colour Match: A colour will never print out to
exactly to match its on-screen source. Colours vary from monitor to
monitor, and different printers produce different colour results. All
these variables affect the printed outcome.
Pleasing Colour: Colour that when printed is close enough to the original
colour requested without becoming an entirely new colour.
Cutting Tolerance: The margin of error that a cutting machine has to cut paper. It can be 1/16 inch
or 1/8 inch. This means the trim line that it is suppose to cut down
can vary up to either 1,61mm or 3,175mm depending on the cutting tolerance
for the order.
Colour Drift: This occurs when a colour shifts away from its original
value and becomes a new colour. It becomes a gradient in a way, it starts with the original colour then blends into a new colour at the end.
Incorrect Colour Selection: This is when you select a colour that doesn't
exist in the colour gamut (the available colours in a certain colour mode) you are using.
In CMYK there are colours that don't exist within the CMYK colour gamut
but exist in another colour gamut such as RGB. They are referred to
as “out of gamut” colours. Out of gamut colours can be
seen when they are either viewed in CMYK mode or in the final output
when they are printed. Often a new or altered colour is seen.
A pair of thin lines that are at each corner of a file
that show where the file ends.
There are two types of orientation, vertical ( up
and down) and horizontal (left to right).
A clear liquid that is applied to a paper to give it a
glossy look. It also protects the ink that is printed on the paper.
Standard printing process used. The process consist
of a plate that makes an inked impression on a rubber-blanketed
cylinder which in turn transfers it to the paper. This is the
printing process used by all major printing companies as well as
newspaper and magazine printers.
Offset vs. Digital Printing:
A new option of printing called Digital
Printing is available and uses a toner based printing method that
burns images on paper at resolutions of 600-800 dpi. We print offset
at 2400 dpi using your converted file using the ICC profile for sheet
Resolution to Submit:
The correct resolution for submitting files is 300
dpi. Which stands for dots per inch. Some programs have it as ppi (
pixels per inch), which is the same value.
Gang Run Printing:
In order to achieve efficiency we use the industry
standard of “Gang run” printing. It is the method used
to place multiple orders onto a single sheet offset sheet.
A coated paper characterized by a glare-free finish.
ICC (International Colour Consortium) Profile Format: “The intent of this format is to provide a cross-platform device profile
format. Such device profiles can be used to translate colour data
created on one device into another device's native colour space. The
acceptance of this format by operating system vendors allows end
users to transparently move profiles and images with embedded
profiles between different operating systems. For example, this
allows a printer manufacturer to create a single profile for multiple
operating systems.” ICC. 1:2003-09
