- store a photograph as a computer file ;
- load the stored photograph into one of the blank boxes.
(b) Lorretta needs to produce a proof colour copy of the leaflet to show to her manager. Describe two features of a printer which would be needed to produce the leaflet.
(a)
- Loretta should use a colour scanner to store a photograph as a computer file by following the given steps:
- She should place the photograph on the scanner bed and use the scanning software on the computer to initiate the scanning process.
- Choose the desired format and resolution for the scan.
- Save the scanned photograph to a specific folder on the computer's hard drive.
- To load the stored photograph into one of the blank boxes on the leaflet, Loretta can use desktop publishing software in the following manner:
- Open the software and create a new project or open the existing leaflet design.
- Locate the blank box where the photograph should be inserted.
- Use the software's "insert image" or "import image" function to browse and select the previously scanned photograph.
- Resize and position the photograph within the box as needed.
(b) Two features of the printer which would be needed to produce the leaflet are:
- High-resolution printing — A high-resolution printer of minimum 300 DPI (dots per inch) is essential to produce a proof colour copy with sharp images and text.
- Color accuracy and calibration — To ensure the printed leaflet's colours match the digital design, Loretta needs a printer with good color accuracy and calibration.
