Glossary of Common Print Terms

1. CMYK (Cyan, Magenta, Yellow, Key/Black):

• Definition: The color model used in color printing. It combines these four ink colors in various ways to create a full spectrum of colors.
• Usage: CMYK is the standard for digital printing, ensuring your photo book or gift has accurate color reproduction.

2. DPI (Dots Per Inch):

• Definition: A measure of print resolution that indicates how many ink dots are printed per inch.
• Usage: Higher DPI means higher resolution and sharper images. For photo books, 300 DPI is typically recommended for high-quality prints.

3. Bleed:

• Definition: An extra margin is added to the edges of your design to ensure that the final print has no white borders.
• Usage: To avoid white edges in your photo book, extend your images or backgrounds slightly beyond the page edges.

4. Trim:

• Definition: The final size of the printed product after excess edges are cut off.
• Usage: The trim size of a photo book is the size of the pages after they have been cut to their final dimensions.

5. Binding:

• Definition: The method used to hold the pages of a book together.
• Usage: Common binding methods for photo books include perfect binding (glued spine) and saddle stitching (stapled spine).

6. Gutter:

• Definition: The inner margin of a page, closest to the binding.
• Usage: Important for photo books to ensure no important content is lost in the binding.

7. Dye Sublimation:

• Definition: A printing process that uses heat to transfer dye onto materials like fabric, metal, or ceramic.
• Usage: Often used for photo gifts like mugs, t-shirts, and photo panels because it produces vibrant and durable prints.

8. Matte Finish:

• Definition: A non-glossy, flat finish that reduces glare and fingerprints.
• Usage: Ideal for photo books or gifts where a softer, elegant look is desired.

9. Gloss Finish:

• Definition: A shiny, reflective finish that makes colors pop but can show fingerprints and glare.
• Usage: Great for photo books or gifts where vibrant color and a polished look are important.

10. Hardcover:

• Definition: A book with rigid protective covers, usually wrapped in a durable material.
• Usage: Provides a premium, long-lasting finish for photo books.

11. Softcover:

• Definition: A book with a flexible, paper cover.
• Usage: A more economical option for photo books, lighter and easier to handle.

12. RGB (Red, Green, Blue):

• Definition: The color model used for digital screens.
• Usage: Images are often converted from RGB to CMYK for printing to ensure color accuracy.

13. Crop Marks:

• Definition: Lines printed on the edges of a document to indicate where it should be trimmed.
• Usage: Ensures your photo book pages are cut accurately to size.

14. Resolution:

• Definition: The amount of detail an image holds, typically measured in DPI or PPI (pixels per inch).
• Usage: Higher resolution means better quality prints, essential for sharp, clear photos in your book or gift.

15. Image Compression:

• Definition: The process of reducing the file size of an image.
• Usage: Important to ensure images are not too large to handle while maintaining print quality.

16. Acid-Free Paper:

• Definition: Paper that is manufactured with a neutral or basic pH (7 or higher), free from acidic compounds that can cause the paper to deteriorate over time.
• Usage: Ideal for photo books and archival purposes as it ensures the longevity and preservation of printed materials without yellowing or disintegration.

17. Buffering in Paper:

• Definition: The addition of alkaline substances (usually calcium carbonate) during the paper manufacturing process to neutralize acids and maintain a stable pH.
• Usage: Buffered paper offers extra protection against environmental pollutants and acids, making it perfect for photo books and archival photo gifts that need to withstand the test of time.

18. Safe Zone:

• Definition: The area within a design that is free from important elements such as text or critical parts of images, ensuring they are not cut off during trimming.
• Usage: For photo books and gifts, keeping key content within the safe zone ensures that nothing important is lost during the cutting and binding process, maintaining the integrity of your design.

19. Ghosting:

• Definition: A faint image or unwanted pattern that appears on a printed product, typically caused by residual ink on the printing press or transfer issues.
• Usage: In photo book and gift production, ghosting can detract from the quality of the final product. Ensuring proper maintenance and calibration of printing equipment can help prevent this issue.

20. Gamut:

• Definition: The range of colors that can be accurately reproduced by a particular device or process, such as a monitor or printer.
• Usage: Understanding the gamut is essential in photo book and gift production to ensure that the colors in your design are within the printable range of the CMYK process, avoiding color discrepancies between digital displays and printed products.

21. Standard Layflat Binding:

• Definition: A binding technique that allows the pages of a book to lay completely flat when open, achieved by using a special hinge at the spine.
• Usage: Ideal for photo books, standard layflat binding ensures near seamless panoramic spreads and full-page photos without losing any part of the image in the gutter, providing a high-quality viewing experience.

22. Deluxe Layflat Binding:

• Definition: A binding technique where pages lay completely flat with a continuous page across the center, allowing for uninterrupted images across two pages.
• Usage: Perfect for premium photo books, Deluxe layflat binding ensures that full-spread photos are displayed without any loss of content in the gutter, offering a flawless and immersive visual experience.
