Uses of Digital Graphics (Purpose & Legal Requirements):
,Digital Graphics Example 1
Purpose: The purpose of the graphic is to inform individuals about the swine flu, aiming to
raise awareness, encourage education, and provide resources for those affected or seeking
more information.
Message: The message this poster is trying to convey includes
important information about the symptoms of swine flu, and
guidance on what to do if someone suspects they have swine flu,
hence providing a link for NHS’s website and contact number to
learn more about the flu.
Target audience: It targets the general population, with a focus on
those at higher risk of complications from swine flu, such as young
children, elderly individuals, pregnant women, and individuals with
underlying health conditions. It may also target caregivers and
healthcare professionals.
Visual elements: The poster should be clear, concise, and easily
understandable. It includes an image of a man sneezing almost covering with his hand which
is relatable in this context, and text written in white, blue, and black and most of them in
capital letters as a warning to grab the people’s attention, and easy-to-read text in a
prominent font. Colours that conveyed seriousness and urgent and used to grab attention.
Legal Requirements: The graphic appears to comply with most legal requirements, but there
may be issues with accessibility under the Equality Act (2010) and Human Rights Act (1998)
particularly concerning individuals who may have difficulty distinguishing between the blue
and white texts. Ensuring accessibility for all users equally, such as using high contrast
colours or providing alternative text for images, is essential for compliance with accessibility
standards.
Digital Graphics Example 2
The purpose of Domino’s graphic is to promote or advertise the
variety of pizzas offered by the company to its target audience. This
aims to attract customers and encourage them to order pizzas from
the company.Message: That posture shows three types of pizzas,
including vegetarian options which will attract individuals including
vegetarians, in addition to pricing and serving sizes, along with the
pricing per serving Additionally, it provides instructions on how to
order from Domino’s
Target Audience: It targets all people including vegetarians as there is
an option for them, especially who enjoy eating pizza with friends and families on normal
days or special events such as parties. Etc
Visual Elements: Domino's Pizza's message is expressed simply by a combination of text and
images, including numbers, to help the target audience understand and see the prices and
, recall the message. The image's dark background attracts attention to the colourful pizzas
and their various toppings, and the price text is coloured to match the logo's colours,
showing the company's identity.
The graphic appears to comply with most legal requirements. However, there may be issues
with accessibility under the Equality Act (2010), particularly concerning individuals who have
trouble distinguishing between reds and greens in one of the pizzas. Ensuring accessibility
for all users, such as using high contrast colours or providing alternative text for images.
Additionally, adherence to copyright designs and patents act should be ensured to avoid any
infringement issues related to the use of images or logos.
Digital Graphics Example 3
Purpose: One of the primary purposes of such a poster would be to
promote "The Walking Dead" comic series. It aims to attract
attention and generate interest among potential readers and fans of
the zombie apocalypse and action genre.
Message: The message shown in this poster is persuading fans to
read the comic, could be one of intensity, conflict, and survival as
the title "All Out War" suggests. It also shows the high stakes and
dramatic narrative elements of the story based on the drawings which will attract zombie
apocalypse and action genre fans.
Target Audience: The target audience would primarily be fans of "The Walking Dead"
franchise who enjoy comic books and general The Walking Dead fans. It also includes
individuals interested in post-apocalyptic settings, zombie fiction, action, and character-
driven storytelling.
Visual Elements: As we can see from the poster, characters are shown in a state of conflict
or facing off each other from their emotions. Dramatic lighting and color schemes used are
purple and yellow to evoke an intense, dramatic mood, and tension, an image of a man on
top of a car surrounded by zombies describing action and survival in a yellow shade.
Legal Requirements: Copyright Compliance: The poster must comply with copyright laws, all
artwork, characters, and other elements featured are either original creations or properly
licensed from the copyright holders. This includes obtaining permission to use any
trademarked logos or symbols associated with "The Walking Dead" franchise.
