Looking to see a sample of the CPP Exam “Piece Of Cake” Study Guide? (You might be thinking, “What is the hype around this “study guide”? I would like to see it myself.) Well…your wish is my command!
Click Here to receive a FREE CHAPTER or read the chapter below.
Chapter 10 covers printers, drivers, profiles, soft proofing, paper choices, ink, and copyright laws. There is a section on panoramic and black and white printing but I did not cover this in the CPP Exam Study Guide. Read the Photography 10th Edition book if you would like more information about these two subjects.
We will cover:
- Printers & Drivers
- Profiles & Soft Proofing
- Papers & Inks
- Copyrights Laws
Printers make our dreams come true. After hours (or minutes) of capturing, backing up and editing our images, then it is time to make our creations come alive on paper.
There are several printers available to print your images: Inkjet, Photographic Laser, Dye-Sublimation, Color Laser, and Film Recorder.
The most commonly used printer for individual photographers is the Inkjet Printer.
TIP: The Inkjet Printer sprays fine droplets of colored dyes or pigments onto paper. TIP: This concept will be on the CPP EXAM!
Problem: Your image is made up of pixels but a printer uses dots. What to do? What to do?
Solution: A DRIVER translates the pixels in your image to dots.
QUICK FACTS ABOUT PRINTERS:
#1 Printers use only 8 bits per channel. (TIP: Memorize this statement about printer channels for the CPP EXAM!)
#2 Printers use SUBTRACTIVE colors (i.e. CMYK – cyan, magenta, yellow, black). We also talked about this in Chapter 8.
PROFILES & SOFT PROOFING
We discussed profiles in the Chapter 8. ICC Profiles allow the computer to tell the printer to print the image color a certain way. We want the computer and printer to “talk” to each other so the printed image looks like the image that was on the monitor.
You want your image on the screen to translate exactly to the printer but there are two issues that prevent this from happening:
#1 A monitor uses transmitted light (glows from within) and a print uses reflected light.
#2 A monitor has a wide gamut of colors compared to most printers.
One way to reduce these two issues is to “Soft Proof” your images. A soft proof will show you the image that your printer or another type of printer can actually produce.
Of course, you need to consider the light that you are viewing the print under.
A good term to know is:
Metamerism – is the change in our perception of a color under different light
sources. (The “skinny” – this means if you view a picture of an apple pie in the sunlight them it might have a slight blue cast to it. If you view the picture of the apple pie in your house with tungsten lights on it, then it might have a slight red/yellow cast to it.)
PAPERS & INKS
There are a variety of papers and inks to use with images. Here are some Quick Facts about paper and inks that are important for the exam.
QUICK FACTS ABOUT PAPER & INKS:
#1 Glossy paper gives the greatest tonal range from black to white. (TIP: Know this for the CPP EXAM!)
#2 Image Sharpness and Color Saturation is more apparent with glossy paper.
#3 Dye-Based Inks provide beautifully saturated colors but fade quickly.
#4 Pigment-based Inks last longer.
TIP: Why is the “K” or Black in CMYK printers?
In theory, the combination of the three subtractive colors should be black but in reality they combined to form a muddy brown – yuck! To ensure that a true black appears on the print, they include the “K” or black cartridge. How about them apples?
There is lots of debate in the courts of how images should be copyrighted and who does and doesn’t have the right to use them. There are some exceptions to the laws. For example:
Fair Use - is an exception to the copyright laws that allows people to use images for educational purposes only. It does NOT protect someone if they use the image in an assignment and then try to sell it in a gallery or online.
TIP: Know the term “Fair Use” for the CPP EXAM!)
