Multiple choice

What is the purpose of the photosensitive emulsion in Solarplate Printing?

  1. To create a resist for etching

  2. To enhance the contrast of the image

  3. To transfer the image to the metal plate

  4. To protect the metal plate from oxidation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The photosensitive emulsion is applied to the metal plate and exposed to UV light, which hardens the emulsion in areas exposed to light, creating a resist for the subsequent etching process.

Multiple choice

What is the purpose of the etching process in Solarplate Printing?

  1. To remove the photosensitive emulsion

  2. To create raised areas on the metal plate

  3. To create recessed areas on the metal plate

  4. To enhance the contrast of the image
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The etching process removes the unexposed areas of the photosensitive emulsion, creating recessed areas in the metal plate that will hold ink during the printing process.

Multiple choice

What is the purpose of occlusion culling in a game engine?

  1. To hide objects that are not visible to the player

  2. To improve the quality of shadows

  3. To reduce the number of draw calls

  4. To optimize memory usage
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Occlusion culling is a technique used to hide objects that are not visible to the player, thereby reducing the number of objects that need to be rendered, which improves performance.

Multiple choice

What is the purpose of the sensitizing solution in cyanotype printing?

  1. To make the paper receptive to light

  2. To fix the image after exposure

  3. To tone the image

  4. To remove unexposed chemicals
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The sensitizing solution in cyanotype printing contains the photosensitive chemicals that react with ultraviolet light to form an image.

Multiple choice

What is the purpose of the fixing solution in cyanotype printing?

  1. To make the paper receptive to light

  2. To fix the image after exposure

  3. To tone the image

  4. To remove unexposed chemicals
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The fixing solution in cyanotype printing removes the unexposed photosensitive chemicals from the paper, making the image permanent.

Multiple choice

What is the purpose of exposing the sensitized paper to ultraviolet light in cyanotype printing?

  1. To make the paper receptive to light

  2. To fix the image after exposure

  3. To tone the image

  4. To create an image
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Exposing the sensitized paper to ultraviolet light in cyanotype printing causes the photosensitive chemicals to react and form an image.

Multiple choice

What is the purpose of washing the exposed paper in water after exposure in cyanotype printing?

  1. To make the paper receptive to light

  2. To fix the image after exposure

  3. To tone the image

  4. To remove unexposed chemicals
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Washing the exposed paper in water after exposure in cyanotype printing removes the unexposed photosensitive chemicals from the paper, leaving only the image.

Multiple choice

What is the purpose of toning the image in cyanotype printing?

  1. To make the paper receptive to light

  2. To fix the image after exposure

  3. To change the color of the image

  4. To remove unexposed chemicals
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Toning the image in cyanotype printing changes the color of the image by reacting the image with a chemical solution.
