Go to\u00a0<b>Tools &gt; Enhance Scans<\/b>\u00a0and add it. In the PDF with scanned text go to Enhance Scans in the Tools pane and select\u00a0<b>Recognize Text &gt; In this File<\/b>.<\/p>\n<h3>Changing background colour<\/h3>\n<div>\n<p>Some people find it easier to read when they have certain background colours. So you should be able to change the background colour of a PDF document. Use\u00a0<b>Edit &gt; Preferences &gt; Accessibility &gt; Replace Document Colours<\/b>. Sometimes this may not work well; for example, if there are background images.<\/p>\n<\/div>\n<h3>Read Out Loud<\/h3>\n<div>\u00a0You can check whether the text can be picked up by assistive technologies by\u00a0<b>View &gt; Read out loud<\/b>. Reading order that was discussed previously (in the series of posts) affects the way content will be read out.<\/div>\n<div><\/div>\n<div>\n<h3>Accessibility Checker<\/h3>\n<p>You can check the accessibility of your document using Accessibility pane&#8217;s <strong>Full Check<\/strong>\u00a0option. This will give you issues that the automatic checker can pick. However, there are many things that this automated accessibility checker is not capable of picking up, for example issues with complex tables. I will discuss complex tables in my next blog post.<\/p>\n<figure id=\"attachment_1515\" aria-describedby=\"caption-attachment-1515\" style=\"width: 272px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/blog.ucem.ac.uk\/onlineeducation\/wp-content\/uploads\/2019\/12\/PDF-Accessibility-checker.png\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1515 size-full\" src=\"https:\/\/blog.ucem.ac.uk\/onlineeducation\/wp-content\/uploads\/2019\/12\/PDF-Accessibility-checker.png\" alt=\"Accessibility pane Full Check option\" width=\"272\" height=\"506\" srcset=\"https:\/\/blog.ucem.ac.uk\/onlineeducation\/wp-content\/uploads\/2019\/12\/PDF-Accessibility-checker.png 272w, https:\/\/blog.ucem.ac.uk\/onlineeducation\/wp-content\/uploads\/2019\/12\/PDF-Accessibility-checker-161x300.png 161w\" sizes=\"(max-width: 272px) 100vw, 272px\" \/><\/a><figcaption id=\"caption-attachment-1515\" class=\"wp-caption-text\">Figure 1: Accessibility checker<\/figcaption><\/figure>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>This is the fourth post of Accessible PDFs series of blogs.
