Printing Terms

Lithographic

Offset lithography is mainly suited to printing illustrated work on a broad range of papers up to 350gsm and it is the main process for most types of printed matter on paper. Lithographic printing is ideal for:

  • Promotional literature, brochures and illustrated books
  • Magazines, newspapers, directories and catalogues
  • Printed stationery and forms
  • Security documents
  • Sheet labels and folding boxboard cartons
  • Spot colours, metallic and pastel colours

Digital

These are just some of the benefits of choosing digital print at Swallowtail Print

  • Our digital print facilities can produce finished material much faster than lithographic printing
  • We can print different versions of the same project within a single print-run, for example, variable data printing
  • We can personalise printed material with names, addresses or other relevant information – all at the same time

Simply tell us your needs and we’ll help you decide the best and most cost-effective printing method.

 

4:0 or 4:1 or 4:4 etc

Refers to the number of colours used per side. Can be referred to as four back zero / four back one / four back four.

4 Colour Process

Technique of printing that uses the four process colours of ink to simulate colour photographs or illustrations. See CMYK.

4pp

A product that has four pages and usually consists of a sheet folded in half. The 'outside right cover' is the first page, the 'inside' forms pages two and three, and the fourth page is the 'outside left cover'. For instance, an A4 sheet folded in half becomes an A5 4pp brochure.

4pp A4

A product where an A3 sheet is folded in half to create a multi-page A4 product. The first page is the outside right front cover, the second page is the inside left, the third page is the inside right, and the fourth page is the outside left cover. It is also known as double A4.

6pp

A product that has six pages and usually consists of a sheet folded into thirds. Each of the six panels are referred to as pages. For instance, an A4 page folded into three becomes a 6pp DL brochure.

8pp

A product that has eight pages and usually consists of a sheet folded into quarters. Each of the eight panels are referred to as pages. For instance, an over-sized A4 page folded into four becomes an 8pp DL brochure.

Binding

Various methods of securing folded sections together and or fastening them to a cover, to form single copies of a book. Used on a spine.

Adhesive Binding

Style of unsewn binding in which the backs of gathered sections are cut off and the leaves are held together at the binding edge by glue.  Also referred to as perfect bound.

Burst Binding

Method of unsewn adhesive binding widely used on paperbacks.  The back fold is burst through (nicked) in short lengths during folding so that the glue can reach each leaf as well as section without having to remove the usual 3mm as in perfect binding, unless PUR glue is utilised.

Due to the fact that each leaf and section is adhered with the glue, burst binding is considered to be a more robust form of binding than perfect binding.

As folded sheets are required to burst through, this method of binding does not lend itself to digital print processes.

Comb Bind

To bind by inserting the teeth of a flexible plastic comb through holes punched along the edge of a stack of paper.

Loose Leaf

Single sheets of paper or board bound together in a ring or similar device, which allows for easy removal or addition of pages.

Perfect Binding

An adhesive form of binding.  Signatures that are folded will have a section of spine cut off with the back edge rougheed, glue will then be applied and the cover attached.

As perfect binding is able to utilise loose sheets, it is a suitable method for binding digitally produced work also.  Perfect binding does not have the same robustness which a burst bound book offers, unless PUR glue has been used.  PUR glue will create a bound book of similar robustness to that of a sewn book.

Spiral Bind

A form of binding using a spiral of continuous wire or plastic looped through punched holes in the documents back margin.  This can be either metal or plastic.

Saddle Stitched

A form of binding that uses staple shaped wires through the middle fold of collated sheets. In saddle stitched work that printed sections are inserted one inside the other on a saddle before stapling along the back fold.

Although dependent on the stock weight, ideally most suitable for books with fewer than 80 pages.

Wire-O Binding (or Wiro)

A metal preformed binding, which is clamped through a series of punched holes on the binding edge.

Wire-O offers a variety of cover options, most common are:

  • Standard Binding – separate front and back covers.
  • Full Canadian – partially hidden wiro is exposed on front and back cover.
  • Half Canadian – wiro is exposed on the back cover.
  • Easel – a free standing triangular cover.

The advantages of wiro binding are:

  • Pages turn easily.
  • Sheets will also stay flat whenever the book is opened (impossible with gluing or stitching).
  • Back to back opening without ever damaging the spine.
  • Secure retention of pages.
  • Perfect registration – ideal for overlays and double page spreads.
  • Different materials and thickness can be combined anywhere in the book.
  • Easy removal or replacement of sheets.
  • Virtually no size restrictions.

Sewn With Drawn On Cover

Providing that extra robustness when required.  A paper or board book cover that is attached to a sewn book block by gluing the spine and then trimmed to final size.

In producing the sewn book block, after gathering of signatures, the sewing machine inserts threads through the spine of each section and then uses further thread to join the sections to each other to form the book block. Sewn books will generally tend to lie flatter when opened as opposed to a burst, perfect or saddle bound book. PUR gluing will provide similar results to that of a sewn booklet.

Black

Blanket

Letterpress

Letterpress printing is relief printing of text and image using a press with a "type-high bed" printing press and movable type, in which a reversed, raised surface is inked and then pressed into a sheet of paper to obtain a positive right-reading image. It was the normal form of printing text from its invention by Johannes Gutenberg in the mid-15th century until the 19th century and remained in wide use for books and other uses until the second half of the 20th century. In addition to the direct impression of inked movable type onto paper or another receptive surface, letterpress is also the direct impression of inked printmaking blocks such as photo-etched zinc "cuts" (plates), linoleum blocks, wood engravings, etc., using such a press.

In the 21st century, commercial letterpress has been revived by the use of 'water-wash' photopolymer plates that are adhered to a near-type-high base to produce a relief printing surface typically from digitally-rendered art and typography.

Ring Binder

The capacity depends on how many sheets are to be accommodated, the thickness of the material and whether or not tabbed dividers are required.

Essentially there are two types of mechanism, round 'O' and 'D'. 'O' rings are fixed into the binder spine and 'D' Rings onto the inside back cover. The 'D' is a little more expensive. The decision to use one or other style of mechanism usually depends on whether or not the binder is to include dividers. The 'D' Ring is designed so that the contents sit flat on the back cover and square on the right hand edge therefore a wider cover is necessary. As the mechanism is riveted to the back cover, the spine area is clear for printing.

The 'O' ring can be fitted to the inside back cover, but this is not common. When it is riveted to the spine it can interfere with the print on the outside and care must be taken at the quoting/artwork stage to ensure the client is aware of this.

Measurements for quoting are Sheet size, Cover size, Spine width, and Flat size.

Most binders use a 2 ring mechanism. The benefit of using a 4 ring is that the content is held more squarely and securely. This is especially important when large amounts of paper are being carried. The 4 ring spreads the weight. Find out how the binder contents are being supplied. If they are coming from their Printer, they will probably be pre-punched. Remind them to advise their Printer accordingly. If the material is being produced in house, they will need a 4 hole punch and most offices only use 2 hole punches.

Binds with 6 ring mechanisms are usually the Organiser type, either A5 or the 'Filofax' size which carries a sheet size 170mm x 95mm wide. Organiser mechanisms usually have triggers for easy opening. As with 4 ring binders, clients need reminding about hole punching. Six ring mechanisms are not available for A4.

The most cost effective ring mechanism is a 25mm capacity 2 round ring. Larger and smaller rings are more expensive. Ring mechanisms can be 'dipped' to a colour, but an exact Pantone match is not possible.

Rotogravure

Spine

How do I know how wide the spine will be?

There’s a simple formula which determines that width. Just take the number of pages in your book and divide that figure by your text paper’s PPI (Pages Per Inch). Where do you get the PPI? It depends on what kind of paper you’re using and it usually appears on the printer’s estimate or quote. If for some reason it doesn’t appear there, ask the printer for it. Let’s say your book has 200 pages and you are printing it on a web press using a paper which has a PPI of 400. Then the width of your book’s spine will be 200 ÷ 400 or half an inch. That’s for a paperback. For a hard cover book, you have to add the thickness of the boards. The easiest way to do this accurately is to have your printer provide you with a template.

Web Offset

A method of printing which uses a continuous roll of paper. They are very fast presses and are only suitable for large print runs on relatively thin paper stocks.

Web offset printing

Web offset is a form of offset printing in which a continuous roll of paper is fed through the printing press. Pages are separated and cut to size after they have been printed. Web offset printing is used for high-volume publications such as mass-market books, magazines, newspapers, catalogues and brochures.

There are two methods of web offset printing, known as heatset and coldset (or non-heatset). In the heatset process, the ink is dried rapidly by forced-air heating. In the non-heatset or coldset process, the ink dries more slowly by ordinary evaporation and absorption.

Some web offset presses transfer text and images to only one side of the print medium at a time. Others can print on both sides simultaneously. The paper width is usually between 11 and 56 inches (approximately 28 and 142 centimetres). The paper is fed through the system at speeds ranging from 5 to 50 feet per second (approximately 1.5 to 15 meters per second).

Web offset printing differs from sheet-fed offset printing, in which individual pages of paper are fed into the machine. Sheet-fed offset printing is popular for small and medium-sized fixed jobs such as limited-edition books.

Web Press

Cylinder printing machine in which the paper is fed from a continuous reel, as opposed to sheet fed.
