Chapter 5 Book Questions

1. Raster image vs Vector

Raster images are bitmaps, which are grids of individual pixels. Vector Images are based on mathematical formulas that show shapes.

2. Resolutions required for digital media and print media

The minimum design image for print media is 72 DPI. The minimum for digital media varies on the image. Banners are smaller than full page spreads.

3. CYMK vs RGB

CYMK - Cyan, Magenta, yellow, and key.

RGB- Red, Green, Blue

4. Pantone colors/ process vs spot color

Pantone colors is used through a color matching system while spot color depends on the selection.

5. Preflight analysis for print and for web

Preflight analysis is the process of making sure all of the digital data that is required to print is there.

6. Font Management / Adobe Type 1 fonts with TrueType

True type helps develop personal fonts.

7. Transparency / Communicate intent to printer

- Where are the transparent elements?

The transparent are located in the WYSIWYG area, and fall into two categories.

- Did they process correctly?

Yes

- Is anything missing in the layers that should show through the transparency?

No

- Are there transparency values that can be adjusted to optimize the overall effect?

Yes

8. Describe six pre-imaging file analysis processes that should be considered when developing a computer graphic for reproduction manufacture.

The Six step pre-imaging process includes:

1. Raster image processing (RIP) technologies that are common to all four manufacturing processes

2. Colour management for repeatability, as a part of the RIP process

3. Trapping to lithographic and flexographic specifications

4. Transparency, which is a visual effect that has a great impact on imaging

5. Imposition for pre-RIP and post-RIP for media utilization

6. Preflight analysis and automation for computer file creation

9. Describe four major imaging technologies that utilize computer graphics to image on different substrates.

Four major imaging technologies that utilize computer graphics to image on different substrates are Colour Profile, Color Prenergy, Adobe Acrobat, and Adobe Creative Applications.

10. Describe the difference between raster data and vector data when creating a computer graphic file.

The difference between raster data and vector data when creating a computer graphic file is that Raster data is made up of pixels while Vector data is used for storing things that have distinct boundaries.

11. Compare the raster resolution of the data for a typical lithographic plate-setter compared to the resolution of a typical inkjet device.

In this comparison, the raster resolution for the data for a typical lithograhic plate-setter compared to the resolution for a typical inkjet device is going to be lower.

12. How many addressable values can be recorded in an eight-bit byte of computer data?

256 different values.

13. What does the acronym WYSIWYG stand for?

"What you see is what you get"

14. What color matching library has been developed exclusively for process color printing inks (CMYK)?

The InDesign and Truematch systems have come out with different libraries, and in this case the Pantone color library has been created to help.

15. What can a page layout artist do to a graphics file if the transparent elements on the page are dropping out or not processing in the RIP?

They can send them into photoshop to create a forever transparent background.
