Manipulating graphic applications is a crucial skill for ICT technicians working in various industries across Kenya, including media, advertising, education, and corporate communication. Mastery of graphic design software enables technicians to create, edit, and manage visual content that supports branding, marketing, and information dissemination. This chapter equips ICT technicians with the foundational knowledge and practical skills required to effectively use graphic applications in professional settings such as county government offices, banks, and educational institutions.

5.1 Identifying graphic design requirements

The ability to identify and understand graphic design concepts is foundational for ICT technicians tasked with managing visual content. This section explores key terminology, the requirements for graphic applications, the types of software used, the kinds of publication designs encountered, and the elements that comprise a typical graphic application window. These insights prepare technicians to meet practical assessment criteria and simulate real-world scenarios effectively.

5.1.1 Definition of terms

Understanding the terminology used in graphic design is essential for clear communication and effective application of skills. A technician who confuses a raster file with a vector file, for example, may send a logo to the print shop at a size where it prints blurred. The following terms are commonly encountered in graphic application contexts.

Graphic design

Graphic design is the process of creating visual content to communicate messages. By applying visual hierarchy and page layout techniques, designers use typography and pictures to meet users' specific needs and focus on the logic of displaying elements in interactive designs to optimise the user experience. Example: a graphic designer at an advertising agency might create posters for a new product launch using graphic design principles.

Pixel

A pixel is the smallest single dot of colour in a digital image. Thousands or millions of pixels placed in a grid form a picture on a screen. Example: a photograph of 1920 × 1080 pixels contains 2 073 600 pixels.

Raster graphics

Raster graphics are images composed of pixels arranged in a grid, each pixel representing a colour value. These images lose quality when scaled up because the pixels become visible. Photographs and detailed images are typically raster graphics, commonly edited in applications like Adobe Photoshop.

Vector graphics

Vector graphics use mathematical equations to represent images through points, lines, and curves, allowing them to be scaled infinitely without loss of quality. Logos and icons are often created as vector graphics to maintain clarity across different media sizes.

The two image types compare as follows.

Resolution

Resolution refers to the density of pixels in an image, usually measured in dots per inch (DPI). Higher resolution images have more detail and clarity, which is critical for print publications, such as brochures produced for a school or college office.

Colour models

A colour model is the method used to describe colours. RGB (red, green, blue) mixes light and is used for screens, while CMYK (cyan, magenta, yellow, key/black) mixes inks and is used for printing. A design prepared in RGB may look slightly different when printed in CMYK, so the technician must know the final output before starting.

Typography

Typography involves the art and technique of arranging type to make written language legible, readable, and visually appealing. Proper typography enhances communication in digital and print media, such as newsletters produced by educational institutions.

Layout

Layout is the arrangement of text, pictures and white space on a page. A good layout guides the reader's eye from the most important item, such as the title, to the details. Example: a flyer for a computer training course places the course name at the top, the fee in Ksh below it and the contact details at the bottom.

5.1.2 Graphic application requirements

Graphic applications have specific requirements that ensure they operate efficiently and meet professional standards. These requirements span hardware, software, and user skills necessary for optimal performance.

Hardware requirements

Graphic design software demands robust hardware, including a capable processor, ample RAM, a good graphics card, sufficient storage and a high-resolution monitor. For instance, a graphic technician in a design and printing shop needs a reliable workstation to handle complex image editing without lag. The table gives general guidance.

Software compatibility

The graphic application must be compatible with the operating system and other software tools in use. Compatibility with file formats such as JPEG, PNG, SVG, and PDF is essential for seamless workflow, especially when files are shared between departments or sent to an outside print shop.

User skill level

Effective use of graphic applications requires users to have foundational knowledge of design principles, software navigation, and file management. Training programmes in institutions like technical colleges often emphasise these skills to prepare students for the ICT field.

Licensing and updates

Graphic applications must be properly licensed to avoid legal issues, and regular updates are necessary to access new features and security patches. For example, an ICT office that keeps a record of its software licences avoids operational disruptions when an audit or renewal is due.

Storage capacity

High-quality graphic files can be large, necessitating sufficient storage solutions such as external hard drives or cloud storage platforms. A design shop that keeps customers' artwork for repeat orders often uses cloud storage to facilitate easy access and backup.

5.1.3 Types of graphic application software

Graphic application software varies depending on the intended use, complexity, and output requirements. ICT technicians must familiarise themselves with the major categories and popular software tools.

Raster graphic editors

These editors manipulate raster images at the pixel level, suitable for photo editing and digital painting. Examples include Adobe Photoshop and GIMP. A technician at a marketing firm might use Photoshop to enhance product images for online campaigns.

Vector graphic editors

Vector editors create and edit images based on geometric shapes, ideal for logos and illustrations. Adobe Illustrator and CorelDRAW are common examples. For instance, a graphic designer at a college may use a vector editor to design the institution's logo and event materials.

Desktop publishing software

Desktop publishing tools combine text and graphics to produce publications such as brochures, flyers, and newsletters. Microsoft Publisher and Adobe InDesign are widely used. An ICT office may use these tools to create notices and information leaflets.

3D graphic software

3D graphic applications enable the creation of three-dimensional models and animations, useful in product design and architectural visualisation. Blender and Autodesk 3ds Max are examples. Although less common in routine ICT technician roles, knowledge of these tools benefits those supporting specialised projects.

Web graphic tools

These applications focus on graphics optimised for web use, including user interface elements, social media graphics and simple animations. Canva is one example. A technician may use such a tool to prepare an online advertisement for a cyber café's services.

5.1.4 Types of publication designs

Publication design involves arranging visual and textual content to communicate effectively to an audience. Various publication types require different design approaches, including page size, amount of text, folding and the distance from which the item is read.

5.1.4.1 Templates

A template is a pre-designed publication file with the page size, margins, fonts, colours and placeholder text already set. The user replaces the placeholders with their own content, which saves time and keeps a consistent look. Example: an ICT department creates a notice template with its logo and standard fonts so that every notice issued from the computer lab looks the same.

5.1.4.2 Banners

A banner is a large-format design printed on vinyl, cloth or paper and displayed at events or outside premises. It is read from a distance, so it needs a short message, very large and bold lettering, strong contrast and artwork that stays sharp when enlarged. Vector artwork is preferred for this reason. Example: a banner outside a computer training centre announcing "New intake open" with a contact number.

5.1.4.3 Booklets

A booklet is a small multi-page publication made from sheets folded in half and fastened along the fold, usually by stapling. Because each folded sheet gives four pages, the total number of pages should be a multiple of 4. Example: a computer lab user guide of 12 pages that explains login steps, printing rules and file-saving procedures.

5.1.4.4 Brochures

A brochure is a folded promotional document that gives concise information about products or services, for example a tri-fold printed on A4 paper that folds into three panels. It needs a clear cover panel, short headings, attractive imagery and contact details. Example: a brochure listing the short courses offered by a computer training centre, with course duration and fees in Ksh.

5.1.4.5 Flyers

A flyer is a single sheet, usually A5 or A4, printed on one or both sides and handed out or pasted on notice boards. It carries one main message, a clear heading, a short body and a call to action. Example: a flyer for a cyber café advertising typing, printing and photocopying services with prices in Ksh.

5.1.4.6 Posters

A poster is a large sheet, commonly A3 or bigger, designed to attract attention from a few metres away. It relies on one dominant image, a bold title and limited text. Bold colours and legible fonts are critical. Example: a poster in a computer laboratory reminding students to log out and shut down computers after use.

5.1.4.7 Cards

Cards are small printed items such as business cards, invitation cards and greeting cards. They have a small page size, so text must be brief and clearly legible. Example: a business card for an ICT technician showing name, job title, telephone number and email address, with the logo on one side.

5.1.4.8 Certificates

A certificate is a formal document that confirms an achievement or completion of training. It is usually printed in landscape orientation on good paper, with a decorative border, the institution's logo, the learner's name, the award title, the date and spaces for signatures. Example: a certificate of completion for a word processing and spreadsheet course.

5.1.4.9 Magazines

A magazine is a regularly issued, multi-page publication with a cover, contents page, articles, pictures and sometimes advertisements. It uses columns, consistent heading styles and page numbers to keep many pages organised. Example: a college ICT club magazine carrying technology articles, student projects and a page of advertisements from local suppliers.

Newsletters

Newsletters disseminate regular updates within organisations. For example, a college ICT department may produce a termly newsletter for staff and learners, requiring consistent formatting, a repeating masthead and readable typography.

Digital publications

E-books, online magazines, and interactive PDFs fall under digital publications. ICT technicians supporting online learning platforms use graphic tools to create engaging digital content accessible on various devices. These are designed for the screen, so RGB colour and moderate file size are important.

5.1.5 Elements of graphic application window

A graphic application window typically contains several elements that enable users to create and manipulate designs efficiently. Understanding these components is vital for effective software navigation.

Title bar

The title bar runs along the top of the window and shows the name of the application and the open file. It also holds the minimise, maximise and close buttons.

Menu bar

The menu bar provides access to various commands and functions organised in categories such as File, Edit, View, and Help. For example, a technician designing a brochure in Adobe InDesign uses the menu bar to save files or adjust layout settings.

Toolbars

Toolbars contain icons representing tools for drawing, selecting, editing, and transforming objects. These allow quick access to frequently used functions, enhancing workflow efficiency. In some applications, such as Microsoft Publisher, the commands are grouped in tabs on a ribbon instead.

Rulers and scroll bars

Rulers along the top and left edges show measurements of the page, helping to place objects accurately. Scroll bars at the right and bottom move the view up, down, left and right when the page is larger than the window.

Canvas or workspace

This is the main area where the design is created and viewed. It represents the virtual "page" and supports zooming and panning for detailed work.

Panels and palettes

Panels provide options for managing layers, colours, properties, and history. Layer management is crucial in complex designs, such as those created by a graphic technician working on multi-layered promotional materials for a training centre.

Status bar

The status bar displays information about the current tool, cursor position, page number and document zoom level, helping users maintain precision in their work.
