What is a paperback?
A paperback book comprises a text block and a card cover which is glued to the text block and then wraps around the front and back. The text block comprises all the internal information you want to have in your book, such as text, illustrations etc. The cover is a heavier card, usually around 200gsm to 240gsm depending on the book. For example a regular book, like a novel, will have a cover in the 240gsm region, whereas a magazine might have a cover in the region of 170gsm.
What size can my paperback be?
One of the great things about Imprint Digital is our ability to print and bind almost any size of paperback book. We are able to print and bind books from A6 (148x105mm) to A4 landscape (297x210mm) and everything in between. If your size falls outside of this specification we still may be able to help but it will need us to do some manual checks and quote differently.
What paper types can I use?
We have a vast range of papertypes to choose from depending on the content of your book. Our most popular papertypes are below;
80gsm Opaque - Good for nonfiction books and good for keeping the costs low. Opaque 80gsm is our cheapest paper and helps with cheap book printing if you are on a budget.
100gsm Opaque - Also good for non-fiction books. As it is a heavier paper than the opaque 80gsm it is better for colour images as there will be less show through. It is more expensive than the opaque 80gsm but only by a little.
80gsm Munken Bookwove White - This is the standard paper for novels and fiction titles. It is a slightly off-white paper with a slightly rough/textured feel. It is also good for ‘bulking’ up the book as it is slightly thicker than the 80gsm and 100gsm opaque papers.
80gsm Munken Bookwove Cream - This is the same paper as the Bookwove White but as the name suggests, this is the cream version. Again this paper is mostly used for novels and for making your books spine bigger.
100gsm Recycled - A popular paper for non-fiction titles. This is our recycled paper which is a white similar to the 100gsm Opaque but has a slightly rougher feel but is smoother than the Bookwove papers.
We also offer a range of coated papers from 115gsm to 170gsm which are good for printing photographs and high quality images. We are able to print any number of pages in a plate section on the coated papers and then insert them into the book. This is a great option if you want to have the text printed on the nice Bookwove paper and have some colour images on 130gsm coated paper.
If you are struggling to decide on the paper you want please visit our blog post on papertypes or get in contact with us directly to discuss your options. If the paper you want is not listed above or on our website, we may be able to order it in.
What cover stock do you use?
Our paperback books are bound to a 240gsm cover board which is then laminated, either matt or gloss as standard, however we can leave the laminate off if you wish. Our 240gsm cover board is matt coated to the outer side and uncoated on the inside. We highly recommend lamination to the outer cover to ensure it has sufficient protection.
We are able to get different card stock ordered in if you want something different for your book, please get in touch directly to discuss options.
What will the spine width be?
In order to bind books as a perfect bound paperback book we need to have a minimum spine measurement of 3mm. For Opaque 80gsm this works out to be 48pp (printed pages) and for the Bookwove 80gsm it works out to be 36pp. If you have a book that is under this page count it will probably be best to have it saddle-stitched as a booklet.
What glue do you use?
Our paperback books use two types of glue depending on the paper used. For regular uncoated paper we use EVA (Ethylene-Vinyl Acetate) and for coated papers or uncoated paper where the print bleeds into the spine of the book we use PUR (Polyurethane Reactive). PUR is a stronger and more durable glue than EVA but it is also more expensive. We have had no issue using EVA glue with our uncoated paperback books, we have been doing it this way for over 20 years and it does mean we are able to have a cheaper manufacturing process.
What extras can I add to my paperback book?
We have multiple extras that can be added to your paperback book;
Embossing and Debossing
If you are looking for something very unique it may be worth thinking about getting your book printed as a hardback book.
Colours that you see on screen and that are produced by digital equipment are normally in RGB (Red, Green and Blue). For printed material, we are only able to print in CMYK ( Cyan, Magenta, Yellow and Black). Therefore, any images, photographs, logos and text need to be supplied in your press-ready document as CMYK. We can convert this on our end if you are having difficulties in doing the conversion but there may be an extra charge depending on how much you need converting.
For the best print quality of any and all images, photographs and logos, the resolution will need to be at 300dpi (dots per inch). We can accept resolutions lower than this but we are unable to guarantee high-quality printing for anything under 240dpi. If you are unsure of the resolution/quality of your content we will be happy to produce sample proofs.
When a font is not embedded in the document, the font information will need to be on the local computer where the document is opened. If this font information is not on the local computer then a substituted font will be used. This is something we need to avoid at all costs. One of the ways to avoid this is to make sure all fonts used in the document are embedded.
Covers and internal files should have 3mm bleed as standard. This is the area outside of the trim area to allow for any movements in printing.
Corner trim/crop marks help us when imposing the files for printing but are not essential as we can easily add these when we impose your booklet.
PDF Press Ready Files
Files should be submitted to us as press-ready PDF files. In some instances, we can accept other formats such as Microsoft Word or JPEG but you will need to contact us first.
