Q

What’s a flatbed scanner?

A

They are useful for producing high quality scans as the original image or text is held still whilst scanned. This often comes as part of a home inkjet printer.

Q

What is cloud storage?

A

Cloud storage offers a method of storing work without needing any physical storage devices. Cloud storage also gives access to their work from any computer that is connected to internet. The amount of cloud storage offered by companies differs. It also provided a useful method of backup storage. It can be set to automatically sync with the contents of a hard drive or network to prevent data loss.

Q

What are three advantages of cloud computing?

A
  • Computers designed solely for cloud computing can be cheaper than desktop or laptop machines because they require less hard drive memory for programs and files as it is stored in the cloud.
  • Only the programs that are required need to be paid for and used, instead of other packages that come reinstalled on a computer.
  • Companies can pay a subscription to a software producer rather than a lathe initial cost followed by additional costs like software updates.

Q

What is a raster graphic?

A

Raster graphics are created using a series of coloured pixels. They tend to be used for photographs or illustrations as colours can be blended to soften the change of one colour to the text. The higher the number of pixels, the better quality raster file.

Q

What are three advantages of raster graphics?

A
  • It is possible to change the quality setting for different types of output. You can change the ppi to reduce the size of the file time so they take less time to load.
  • Suitable for photographs because they show detail in gradual colour changes.
  • Can be edited using common photo editing programmes.

Q

What are three disadvantages of raster graphics?

Study These Flashcards
A
  • Images can become pixelated when increased in size.
  • Can be less suited for large size print projects due to a loss in quality when resizing.
  • Very complex raster images are difficult to convert to vector file formats.
22
Q

What is a vector graphic?

Study These Flashcards
A

They use mathematically defined areas to produce the shapes contained within the image.

23
Q

What are three advantages of of vector graphics?

Study These Flashcards
A
  • Can be resized to a far larger image without loss of image quality.
  • You can easily to edit the colour and various parts of the file.
  • They have a smaller file type than raster files.
24
Q

What are three disadvantages of a vector graphic?

Study These Flashcards
A
  • Cannot be used for photographs.
  • Not suitable for images with gradual tonal changes with blended colour.
  • Only specialised software packages can be used to create these types of graphics.
25
What is a registration mark?
It is used to ensure perfect alignment of colours on a page. When printing with the CMYK method, a CMYK printing register mark is visible to allow the colours to be checked.
26
What a colour bar?
A colour bar printed outside the trim area and are used to check the accuracy of the colours being printed.
27
What is a crop mark?
They are small marks at the corners of the finished page to show where the page should be trimmed.
28
What is the bleed area?
The bleed area described the part of the paper outside the crop marks to which the images and features are printed. The bleed area is removed when the pages are trimmed.
29
What is a print run?
The print run is the number of copies of a newspaper or magazine that are printed at a time.
30
What is a CMYK colour palette?
It stands for cyan, magenta, yellow, key. It is used when a document is going to be printed. The colours must be aligned properly otherwise the images will appear distorted.
31
What is a RGB colour palette?
It stands for red, blue, green. It is used on on screen document.
32
What are advantages of digital advertisements to advertisers?
- It is environmentally friendly as ink and paper are not required. - Adverts can be changed regularly, cheaply, quickly. - Adverts can use moving images to attract attention.
33
What is The Paperless Office?
It’s a huge benefit to industry with the use of computer and there has been a reduction in paper use. Important documents are held on computer systems.
34
What is remote working?
DTP work and other files can be shared immediately through the use of email systems. Employers can work from home or in seperate offices on the same item of work. Storing data on a single drive or server allows different people in different places to work on the same document. This allows companies tonhage international offices working on documents simultaneous to increase production and make use to the skills of a varied workforce. This means that companies can become global around the world by connected by different networks. You can communicate with anyone through a variety of platforms.
35
What are safe practices to partake in when using DTP.
- Adjustable seating and footstools and wrist rests. - Offices must be suitably lit with non glare lighting and regular breaks must be taken from the computer screen to avoid headaches and eye strain. - Tidy workspace and cables should be arranged carefully.
36
What are some DTP packages that are available?
- Adobe InDesign - Scribus - Pages
37
Why is CAD animation useful?
Animations allow a user to see how a product looks or moves. They are used as a communication tool. The client will often wish to see an animated video to understand how a product works.
38
What is CAD simulation and what is it used for?
They allow a user to interact with a product. A flight simulator can be used to train pilots without risk of crashing a plane. They can also be used to test the strength of a product without lots of expensive physical models needing to be used. A large number of physical factors can be controlled, such as temperature or wind strength.
39
What is 3D printing?
There is almost no limit to what can be produced to what can be produced using a 3D printer straight from a drawing. This reduces manufacturing costs for the companies involved and can print any shape without any expensive tooling requirements.
40
Advantages of soy ink and wax ink
They are safe, sustainable, renewable and environmentally friendly.
41
Advantages and disadvantages of 3D printing
Accurate, complex design, can test the design, visual display. Expensive start up costs, repair issues and need maintained, can be a slow process.
42
Advantages and disadvantages of touchscreen devices
They are much faster, easy to use, accessible to everybody. They break easily, may slow down over time.
43
Advantages and disadvantages of remote working?
Easy to send electronically to relevant people, can work with different people in different locations, no need to travel. Not in office for up to date information and may not have access to all files.
44
Advantages and disadvantages of the paperless office
There is a possibility of smaller offices, files are backed up, easier to find in the electronic system. Virus may affect files, prone to hacking.
45
How can packaging be reduced?
Make it from biodegradable material, use environmentally friendly inks, reduce the amount of material used.
46
Advantages of a web page over posters
No ink is used, no paper is used, no transport for posters,
47
What are advantages of DTP softwares?
Easy to edit, images can be manipulated, variety of fonts, range of colours.
48
Advantages and disadvantages of cloud computing
Easy to share, can access on multiple devices, no flash drive needed. Hack issues, security details can be leaked, limited storage.
49
Advantages and disadvantages of CAD
Can be more accurate than hand drawn designs, you can easily modify existing ideas. The software itself can be initially expensive, staff need to be trained to use, requires a PC.
50
Advantages and disadvantages of digital rights management
No project should be, people need to purchase your work if they want to use it with is a good profit, protects the rights of the copyright holder. Copying content is not allowed, cannot access the product using multiple devices even if one owns them all, cannot select and copy text to city in research work.
51
Advantages and disadvantages of file management
Storage kept tidy, accessible, always in order. Cant have two files of the same name, knowlege of what is within the folders.
52
How to you prevent copyright?
Put a watermark on the image, register it to your name, or put a copyright symbol on it.
