Which file type uses lossy compression?
JPEG
PNG
TIFF (uncompressed)
SVG
What is the main advantage of lossless compression?
No data is lost during compression
Files are always smaller than lossy files
It increases image resolution
It changes the color model

GIF (animated)
MP3
Explain when you would choose a vector file over a raster file for a design project.
When you need to scale graphics to any size without losing quality
When you want to use photographs
When you need to use a lot of colors and gradients
When you want to compress the file as much as possible
A client wants a logo that can be printed on a billboard and a business card. Which file type should you provide?
Vector file (e.g., .AI or .SVG)
Raster file (e.g., .JPG)
Animated GIF
.BMP
If you are preparing an image for a website, which color model should you use and why?
RGB, because screens use red, green, and blue light to display images
CMYK, because it is used for printing
Grayscale, because it loads faster
Pantone, because it is more accurate
You are designing a magazine cover for print. Which color model should you use?
CMYK
RGB
HSL
LAB
Which scenario best demonstrates the use of lossy compression?
Saving a photograph as a JPEG to reduce file size for web upload
Archiving a logo as a PNG for future editing
Printing a high-resolution poster from a TIFF file
Creating a vector illustration in SVG
A designer needs to send a file to a printer that requires both high resolution and the ability to edit the image without losing quality. They should use (a) .
A client wants to use a photo for both web and print. What steps should you take to ensure the best quality for each use?
Prepare two versions: one in RGB for web, one in CMYK for print, adjusting resolution as needed
Use the same JPEG file for both
Only change the file extension
Use a vector file for both
You are given a logo in JPEG format and need to use it on a large banner. The best course of action is to (a) .
A client complains that their printed images look blurry, but they look fine on screen. What is the most likely cause?
The images have low resolution (low DPI/PPI) and are not suitable for print
The images are in the wrong color model
The images are vector files
The images use lossless compression
You are tasked with designing a brochure that will be printed and also shared as a PDF online. How should you prepare your images and files?
Use CMYK color model and high-resolution images for print, and create a separate RGB, web-optimized PDF for online sharing
Use only low-resolution images in RGB for both
Use GIFs for all images
Only use vector files
Which are used to create a vector image?
Vector shapes
Pixels
Mathematics
Paths
Which are used to create a raster image?
Vector shapes
Pixels
Mathematics
Paths
(a) Converts an image stored by a geometric formula to pixels

Which type of graphic tends to have larger file sizes when containing complex designs?
Vector
Raster
Depends on the complexity
File sizes are generally the same
Which type of graphic is defined by mathematical equations?
Vector
Raster
Both
Neither
Which type of graphic is pixel-based?
Vector
Raster
Both
Neither
For high-quality printing, which graphic type is generally preferred?
Vector for its clear lines
Raster for its detailed imagery
Both, depending on the printing technology
Neither, as printing quality is not affected by graphic type

When considering the creation of digital art, which graphic type offers more freedom for blending and shading?
Vector
Raster
Both offer equal capabilities
Neither offers this capability
Organize these options into the right categories
.jpg

.png
.eps
.ai
.svg
.raw
.psd
Match the correct definition with the term.
Formats capture all of the data of your original file. Can be resized & not lose any data.
Raster
Reduces file size by permanently removing some of the original data, leading to a loss of quality, but resulting in significantly smaller files that are faster to store, send, and stream.
Lossy Compression
Uses mathematical equations. Can be scaled to any size without losing quality or clarity, making them ideal for logos and other graphics that need to be displayed at various dimensions.
Vector
Images made up of a set grid of dots called pixels where each pixel is assigned a color.
Lossless Compression
A client asks you to print out a giant billboard for her business. The graphics has high quality graphics, what kind of file is best for this type of work?
(a)
You want to upload some pictures onto your website but the file size is too big to upload. What kind of compression process can you do in order to manage to size down your file size?
(a)
