Progress challenge 4
Technical report
By Colleen Sedgwick
This progress challenge requires you to create a technical
report to verify if your designs were able to comply and address the technical
requirements of the project. To do this, submit the following:
A written description showing how the resolution
and colour mode of the digital design file would comply and address technical
requirements of the project if it were to be delivered as electronic and
printed adverts.
A written description showing a situation where
you will need to save your design files as PDFs.
A written description showing a situation where
you will need to save your design files as GIFs.
A written description showing a situation where
you will need to save your design files as JPGs.
TIP: Navigate to the student
forum to engage in the discussion with your peers
Answer
Depending upon your exact design, it is better to have a
vectorised version of a digital design file rather than a rasterized one: the
reason being is that rasterized images are built of pixels and become all
blotchy (i.e. pixelated) when you try to increase the size of the image. Vectorised images have the advantage over
rasterized ones because they are made of points and paths and you don’t lose
out on quality when you increase the size[1].
Colour modes – RGB (red, green and blue) colour modes are
best for electronic adverts while CMYK (cyan, magenta, yellow, and black) are
best for printed adverts[2].
To save design files in the following formats, here are
the situations where you need to do so[3]:
As PDFs: if one is to save a document as a PDF
(or Portable document format), the document is often one consisting of multiple
pages, a lot of text and may have both raster and vector images.
As GIFs: to save as GIF (Graphic Interchange
Format), files consist of indexed colour (which means it will save as a maximum
of 256 colours) and are good for simple illustrations, logos and to upload to
websites (particularly as a moving image that is not a video).
As JPEGs (JPGs): JPG (Joint photographic expert
group) files are images which are built as the result of compressing images,
making it easy to share these images without losing quality; one can upload photographs
and similar images quickly and easily via a website.
