Red, green, and blue (RGB) are the primary colors of light. Cyan, magenta, yellow and black (CMYK) are the primary colors of printing. RGB color is used to display on your computer screen. RGB is called additive color. The more light you add the lighter your color becomes. When equal amounts of the RGB primary colors are at their highest level, the resulting color is white. CMYK color is used for printing. Dots of ink are printed on paper for each color: cyan, magenta, yellow

Color pointers from Leatrice Eiseman's Guide to Communicating with Color : When two variations of the same color, one light and one dark, are printed next to each other, the lighter shade will seem lighter, and the darker shade will appear to be darker. Large color areas influence smaller color masses. If a small square of medium gray is surrounded by a larger area in black, the gray square will appear brighter than the same square surrounded by white. The human mind connects

Delete extra colors from your document to simplify prepress work Delete all non-used colors. Going through this process will eliminate the possibility of incorrect conversion of “extra” colors to four-color process. Do not use RGB colors in your document. RGB describes computer monitor color and must be converted to reproduce on paper. When using Pantone colors, use consistent color names in your documents Use correct and consistent names within a file and from project to pro

A Breakdown of Printing Costs The percentage cost for producing 10,000 copies of an 8-1/2" x 11" saddle stitched 16-page self cover booklet that prints eight pictures in four color process breaks down as follows: Research and copy 15% Art and composition 38% Prepress work 17% Paper 8% Printing and binding 13% Mailing and postage 9% Of course, if the number of copies required changes, the percentages would also change.

What are the statistics of paper consumption in the U.S.? The U.S. is the largest market for paper products in the world, producing 90 million tons of paper annually. In turn, the U.S. consumes about 100 million tons per year. In 2012, recycling awareness led to 65% of domestic paper being recycled. This collection effort and the use of post-consumer pulp resulted in recycled paper making up 33% of the nation’s paper making materials. Wood chips and sawmill scraps account for

Why print, paper and pencil remain highly effective learning tools.

The Fact: Sustainable forest management benefits people and the planet. While it’s true that collecting used paper and recycling it into new products is good for the environment, there’s a catch. The wood fibers in paper can be recycled only about five times before they get too weak and break down. That’s why we need fresh fiber harvested from responsibly managed forests, too. Using fresh fiber creates a sustainable cycle of high-quality recyclable material to continually rep

We’ve all had that beautiful project: the one with the solid ink coverage that wrapped around from the front cover to the back cover. It was truly a picture of joy and happiness - until it was folded. Then it became unsightly because of the cracking and show through of the paper under the ink coverage. What do we do now? Let’s go back to the beginning, to the planning stages and maybe something will come up that can help us save this project. Here are some points to consider:

Stocks that have the same front and back surface save money Work-and-turn press forms require one set of plates that can be used to print both the front and back side of the press sheet. The requirement is that both sides of the press sheet have the same surface. If the press sheet has two different surfaces, i.e. a coated one side (C1S) cover stock, then a sheetwise press form would have to be used requiring one set of plates for the front side and a second set of plates for

Opacity refers to the property of paper which obstructs the passage of light and show-through of printing. This characteristic is expressed as the percentage of visible light that does not pass through a sheet of paper. For example, 98% opacity means that 98% of the light can not pass through the sheet, and is absorbed in or reflected by the paper’s surface. Low opacity means the paper will have more show-through, such as tracing paper. High opacity means there will be less s

The paper you use is a critical factor in the appearance of your printed projects. For most of our products, Castle Press has suggested paper options to those most popular for the usage. There are hundreds of different paper brands, colors and weights available depending on the budget for your project. About Paper Options There are three attributes that differentiate papers from one another: finish, weight and opacity. Finish Finish refers to the texture, feel and appearance
