Hairlines
Hairline strokes are device dependent, so they output at different stroke thicknesses on different devices. Use 0.25pt instead.
Texture & Postscript
These can print with unexpected results. If you use them ensure that you have checked them carefully prior to creating your PDF.
Borders
Any small movement at the guillotine stage will make the borders on small items look uneven. If you add a border then thicker borders are less likely to look uneven.
Watermarks
The lowest tint we can print Offset is 5% per CMYK channel. Digital, Large Format and Ink on Fabric have a minimum tint of 10%.
Image Types
All the major file types are supported within your PDF: PSD, tiff, eps and jpg.
RGB & Duotone
We recommend converting to CMYK before creating your PDF.
Gradients
A limitation of gradients is that they can exhibit banding. Short gradients or gradients with colours close together on the colour spectrum work best.
Layer Effects & Transparency
If your file contains any vector layer effects, transparency effects or opacity changes then ensure that your PDF has rendered these correctly when exporting your artwork to PDF.
Overprint
Most vector elements, with the exception of black text and our special finishing elements, should normally be set to knock out. If you use overprint then check the PDF to ensure that the desired effect will be present.
