Trim is the border of your artwork specifying where it is to be cut. It defines the final size of the piece. “Trim” and “Crop” are interchangeable terms. Trim lines are represented by a vertical and horizontal hairlines marked on each corner of the page (see example below). In layout programs such as Adobe InDesign, when you export your artwork to PDF, a dialogue box asks if you want to include Crop and Bleed marks. Tick both of these then specify how much bleed, in this case 2.5mm.
Bleed is a printed area that extends beyond the trim. Allowing 2.5mm bleed guarantees that you won’t see a thin white line if the piece is cut a fraction to the left or right. It is basically and extra 2.5mm of artwork on all edges to safeguard against shifts when trimming. Layout programs give you the option to include Bleed Marks when exporting PDF’s so we ask that you include these, as well as Crop Marks.
The Safe Text Zone is a 2.5mm buffer zone within the trim line that ensures important text or graphics are not cut off when the document is trimmed down (see below). Our print registration and finishing equipment is extremely accurate however it is best practice to include 2.5mm bleed and 2.5mm safe text buffer.
Why do I need to supply my artwork in CMYK?
While computer screens and digital devices display colours in RGB format (Red, Green, Blue), the 4-colour printing process uses CMYK (Cyan, Magenta, Yellow and Black). The range of RGB colour combinations available to view on a screen is much greater than the range that can be printed on paper. As such, if artwork is supplied in RGB format, the printed result will look “duller” and with less contrast than you intended. We always recommend you preview your artwork in CMYK format, then adjust the colour palette as close to your intended output as possible.
If your design has medium to large areas of solid black, we strongly recommend you use Rich Black to ensure a nice solid result. 100% black tends to wash out in comparison to other CMYK elements in the design.
A good mixture for Rich Black on heavier stock weights is: 50 / 50 / 50 / 100. For lighter stock weights use 30 / 0 / 0 / 100. It is also safe to use Rich Black for text above 7pt+ – our printing is of such high quality that registration issues are not an issue.
