SECTION B: DESIGN ASPECT (25 marks)

Read carefully the Thematic Situation presented below. Refer to this theme for Section B and Section C.

Theme: The Advertisement Industry Advertisement & signage companies can help promote a brand by producing

graphic products like signs, posters, merchandise, shop displays and other bespoke (one-off) products, designed to impress. Advertisement involves mainly: Custom-made signs and displays (mainly 3D) and 2D print or digital

advertisements. Mechanisms, electronics and light functions are sometimes also used to increase the impact of such designs.

9. The following preliminary sketch was drawn by a fellow

designer to explain to a shop owner how a 3D, illuminated

(with A.C. mains voltage, powered light), ARROW SIGN could

look for a teenage clothing shop. Such sign is about 1m wide.

In the space below answer the following THREE questions:

a. Design a new 3D sign using another popular symbol that teenagers are

familiar with. (E.g.: @, #, the thumbs-up symbol etc.). Your design needs to

be in 3D that includes ANNOTATIONS and LABELS which describe the features

of the illuminated sign. The symbol needs to be made of ONE shape or text

character only.

b. Add illustrations that show how such a sign can be hanged to a wall.

c. Include details for the type of light that this sign will use.

(6 marks)

(1 mark)

e. The shop owner decided that the sign was to become the image of their new

advertising campaign. In fact, they are analysing 2 ideas for further

promotion of the shop using the sign symbol. However, they also want to

know how every suggestion effects the environment.

Thomas: “…I would like that the sign illumination would change colours to be

vibrant for teenagers!”

Andrea: “It would be cool if the sign could have that old vintage look/style as it

matches current trends” (age 18, Surveyed on 20th December 2018, Sliema.)

Martha: “…this sign is too plain and adds no value to the shop whatsoever”
