File and Quality Validation Process

The file validation process guarantees the compatibility of your files with the printing process, aiming to amend any errors that might have occurred before going to print. Pulsio Print provides several options.

Electronic proofs

Due to our high standards of control, we use the electronic proofs 99% of the time. That also saves time and transport expenses. The electronic proofs are the final, print-ready files of the interior and cover that we send to our clients for final approval before they are uploaded for print.

Digital proofs (cromalins) 

We use digital proofs (cromalins) to check the registration of the colours of the cover or the content. You could also send us digital proofs so that we can comply with your special requirements. Alternatively, we could courier you digital proofs for validation. Depending on the number of digital proofs, the shared expenses are between 20GBP and 60GBP for a digital proof of the cover or a section of the book.

Wet proofs 

Wet proofs are the most accurate way to see exactly how your finished product will look after print. This is also the most expensive type of proofing. This is due to the fact that instead of making an approximate of how the final print job will look (something that happens with Digital Laser Proof/Dry Proof), here the actual print plates have to be prepared. A book set-up and calibration of the machines has to be done as well. The print run is done by skilled print professionals.

However, bear in mind that the wet proof will cost you less than having to reject a print run of a thousand books if the colours are off, or a last-minute alteration is needed. If you’re printing designs that require speciality colouring or inks, or testing a new paper – wet proofing is an ideal way to ensure accuracy and clarity. It is recommended for more specialised jobs such as high-quality art books, full colour or B&W photo books.

We use the exact same materials and colours to create the proof that we will for the job, even down to the exact same inks. We take your reprographic files to perform a print ‘test run’ to get an accurate idea of how everything will come together in your final packaging so you can feel confident going to press. Aside from these benefits, wet proofing is also helpful as you don’t need to attend the first print press, and quality issues can be excluded.

(1) Once you decide to accept the proof, the same print plates are used to make the final print run. (2) If you reject the proof, the changes have to be applied, and new print plates will have to be made.

Wet proof cost, for 1 side 4 colours print (4/0) of a 70×100 cm sheet, is 200GBP, but we offer it to our customers at 100GBP (transport costs included).

Blank dummy 

In some cases, we might produce a blank dummy of a book or a catalogue using the actual materials for the job. That allows the client to see the folding, gathering and binding of the product and its actual size. There is a 50 GBP participation in the expenses.

Set of printed and folded sheets for approval / Check copy

In this case, you receive a set of printed and folded sheets for approval prior to binding for you to make a final check and make changes, if necessary. That type of proofing is usually used for upmarket and exclusive products. A 30GBP customer participation in the expenses is appreciated.
