Q.1

(A)  Fill in the blanks (2)

1. The full form of JPEG is ___Joint Photographic Experts Group_________________________________________________

2. _GIF, PNG, BMP, TIFF, TGA, and JPEG 2000_______ file format can give us transparent background.

(B) Explain about cool colors. Give any 2 color names which are known as cool color.

ans. blue, green, and purple (3)

(C) Explain 5 differences between raster & vector.

ans. Here are five key differences between raster and vector graphics:

1. File Composition

• Raster: Made up of pixels (tiny squares of color) arranged in a grid.

• Vector: Comprised of paths defined by mathematical equations (lines, shapes, curves).

2. Scalability

• Raster: Loses quality and becomes pixelated when scaled up.

• Vector: Can be resized infinitely without any loss of quality.

3. File Size

• Raster: Typically larger due to storing information for every individual pixel.

• Vector: Usually smaller, as it stores mathematical formulas instead of pixel data.

4. Best Use Cases

• Raster: Ideal for detailed and complex images like photos.

• Vector: Perfect for logos, icons, and graphics that require scalability.

5. File Formats

• Raster: Common formats include .jpg, .png, .gif, .bmp.

• Vector: Common formats include .svg, .ai, .eps, .pdf.

Q.2

(A)  Fill in the blanks (2)

1. A ___Point_______ is the smallest and most basic design element.

2. ____Line______ represents a single dimension, length.

(B) True and false (3)

1. Red color is known as primary color. > true / false (True)

2. The intensity of a color is described as saturation. > true / false (True)

3. The color range of RGB is from 0% to 100%. >  true / false (False)

(C) Explain 5 differences between RGB & CMYK color modes.

ans. Here are five key differences between RGB and CMYK color modes:

1. Color Model

• RGB: An additive color model where colors are created by combining red, green, and blue light.

• CMYK: A subtractive color model where colors are created by combining cyan, magenta, yellow, and black inks.

2. Primary Use

• RGB: Used for digital screens and electronic displays, such as monitors, TVs, and smartphones.

• CMYK: Used for printing purposes, such as posters, brochures, and books.

3. Color Range

• RGB: Has a wider color gamut, allowing for more vibrant and bright colors.

• CMYK: Has a narrower color gamut, which may result in less vibrant colors compared to RGB.

4. Color Representation

• RGB: Values range from 0 to 255 for each color (e.g., 255, 0, 0 for pure red).

• CMYK: Values are represented as percentages (e.g., 100% cyan, 0% magenta, 0% yellow, 0% black for pure cyan).

5. Output

• RGB: Designed for light-based devices, so it appears brighter on screens.

• CMYK: Designed for ink-based media, so colors may look duller when printed compared to their digital

Q.3

(A)  Fill in the blanks (2)

1. ___Circle_______ is considering as Basic shape.

2. Shapes can be ____organic______ or geometric.

(B) What kind of information a Visiting card can hold?

ans. A visiting card, also known as a business card, typically contains the following information:

Essential Information

1. Name: The individual’s full name.

2. Job Title: The designation or role of the individual.

3. Company Name: The name of the organization or business.

4. Logo: The company logo for branding purposes.

5. Contact Information: Phone number, email address, and website URL.

Optional Information

6. Address: Office or business address.

7. Social Media Handles: Links to professional profiles (e.g., LinkedIn, Instagram).

8. Tagline/Slogan: A short, catchy phrase representing the business.

9. QR Code: Links to additional information, portfolio, or digital contacts.

10. Fax Number: If applicable, for traditional communication.

Design Elements

11. Color Scheme: Reflecting the company’s branding.

12. Background Design: Patterns, textures, or minimalist designs.

(C) What is DPI? Explain the concept of resolution. 

ans.What is DPI?

DPI stands for Dots Per Inch and refers to the number of individual dots of ink or pixels that can fit into a one-inch space. It is commonly used to measure the resolution of printed images or digital screens.

• Higher DPI: Produces sharper and more detailed images (e.g., 300 DPI for high-quality printing).

• Lower DPI: Results in lower-quality images that may appear pixelated or blurry when printed or enlarged.

Concept of Resolution

Resolution defines the level of detail in an image and determines its clarity and sharpness. It is influenced by the number of pixels or dots that make up the image. Resolution is typically measured in:

1. Pixels per Inch (PPI):
   
   

• Used for digital displays and images.

• Higher PPI means more pixels per inch, resulting in finer details.

2. Dots per Inch (DPI):
   
   

• Used for printed materials.

• Higher DPI ensures crisp and detailed prints.

Relationship Between DPI and Resolution

• Digital Media: Resolution refers to the total pixel dimensions (e.g., 1920 x 1080).

• Printed Media: Resolution is determined by DPI, as it dictates how the digital image translates into physical dots on paper.

For example:

• A 72 DPI image is suitable for web use, where screen resolution is lower.

A 300 DPI image is ideal for professional printing to achieve high-quality results.
