We offer three different Artwork Services: Just Print, File Check and File Assist.

• Just Print is our free option where your print ready PDF will be printed as supplied. We recommend this service only to individuals who fully understand our print ready requirements, who are completely confident that their PDF files have been supplied correctly.
• File Check is a safety net option, where the print ready files are double checked by our Pre Press team before being sent for printing. Prices start at £2.50 + VAT. You can also order a PDF Proof for an additional £4 + VAT.
• File Assist turns any finished design into a print ready PDF and includes a PDF Proof. Prices start at £15 + VAT. 

Please refer to our Artwork Services downloadable PDF guide to see what is included in each of our artwork services.
