I want an environmentally friendly book. What can
Worzalla do to help?

How is the trim size of the book determined?

Trim size is subjective.  Worzalla has produced books as small as 3-1/4” X 4-5/8”, as large as 13” X 15”, and everything in between.  It may help to go in a book store and “feel your options” to determine what you envision for your project.  Your designer would also be a great resource to help determine what my work best for you.  There are certain sizes that are more efficient and cost effective for different binding styles, so flexibility may save you money in the long run.

I want full color printing. Why did you quote only
four colors?

Printing presses only use four colors to produce full color printing – Cyan, Magenta, Yellow and Black (CMYK).


Of these four colors, many colors are possible using varying size dots of each of the four colors. Look closely at a picture in a magazine to see an example (you may need a magnifying glass).

What are Pantone inks?

Pantone inks are used to create a wide array of colors. When a precise color match is most critical (for example when printing a corporate logo), typically a Pantone color is used. Instead of printing this logo as four inks (C,M,Y,K), it can be printed as a single Pantone ink. The printing process is much more cost-effective and easier to control with one ink vs. four. Also because CMYK inks are not able to produce certain vibrant colors Pantone inks are more appropriate in these situations. Pantone inks can also be metallic or fluorescent, which is not possible with CMYK inks.

Is white a color?

White inks may be used in some specialty applications. In most book printing, white is simply the color of the paper being printed. Something referred to as black and white would usually print as black ink only.

How many millimeters are in an inch?

One inch = approximately 25.4 millimeters.

What does oblong mean?

Oblong is when the width of the book is larger than the length of the binding edge. Also called Landscape.

What is the difference between a page and a sheet?

A page is a single side of a sheet. A sheet has two sides, and is made up of two pages.

What is a gutter?

This is the section of the page closest to the spine. Images or text placed near the gutter become difficult to read without opening the book to its maximum.

What are your minimum quantities and why?

2,000 copies is our minimum. While we can print less, the cost is usually the same for 2 copies as it is for 2,000. Higher quantities will result in lower unit costs for the customer.

What is a case?

A case is cloth or paper wrapped over board, which encloses the book block.

What is a book block?

Folded and gathered signatures that are bound with glue, staples, or sewn, but have not received a case or cover.

What is a jacket?

A jacket is a sheet of laminated, printed paper that wraps around the case as a dust cover.

What is an oversized jacket?

An oversized jacket is a single file used to create the case, and the jacket. This usually results in a cost savings for the customer since the jacket and cover are essentially on the same sheet through the press.
