Practical publishing guidance based on Megal Publisher’s documented page, text, image, table, review and output tools.

Practical workflow

Work through the publication in a fixed order

Separate content, structure and proofing decisions so a late correction does not undo earlier work.

Start with meaning and order

A reader should be able to identify the purpose of the poster, navigate its sections and understand the required action without decoding the visual design. The intended audience is people seeing a message briefly from several steps away, and the goal is to make one subject, date or action recognisable at viewing distance. Use descriptive headings for dominant headline, event or proposition, date and location, one response route and organiser or sponsor identity and keep their reading order logical in both the page layout and exported document.

Make text readable

Use substantial type sizes and short line lengths, with secondary details clearly subordinate to the main message. Check font size at final output size, line spacing, paragraph width and contrast. Do not place essential text over a photograph unless the contrast remains dependable across the whole text area. Avoid using colour, capitals or decorative type as the only way to distinguish warnings, categories or actions.

Describe images and structure data

Choose bold imagery with enough quiet space for text, and avoid low-resolution sources that will fail when enlarged. Add concise alt text to informative images that explains their purpose in context. A caption is not always a substitute because it may serve a different editorial role. For data, dates, venue, booking route and sponsor names must be final before the high-resolution file is released.. Use real table headers where row-and-column relationships matter and do not simulate structure with spaces.

Use checks as a review aid

Megal Publisher’s Accessibility Checker reviews publication title and language, picture alt text, colour contrast, empty text boxes, very small text, table structure and PDF-tagging considerations. Treat findings as prompts for human review rather than automatic approval. Use high contrast and plain wording so the poster can be understood quickly and without colour distinctions alone.. PDF export includes a tagged structure tree, but it is not claimed as PDF/UA-certified; verify reading order and semantics in the final file.

Use before sign-off

A short working checklist

Accessibility review checklist

  1. The publication has a meaningful title and language.
  2. Headings describe content and follow a logical sequence.
  3. Body text, captions and conditions remain readable at final size.
  4. Colour is not the only way information is distinguished.
  5. Informative images have useful alt text.
  6. Tables use genuine headers and a simple reading order.
  7. The final PDF is reviewed for its intended accessibility requirement.
Keep the source and proof together. Megal Publisher can keep the page objects editable in an .mpub project. Preserve the source facts and the approved output as separate records so later changes can be checked.
