I logged into GrackleDocs Grackle GO (external website) and went to the dashboard

Grackle Go dashboard

I then uploaded the PDFs I wished to test

Uploading PDF to Grackle Go

The file was uploaded

File uploaded into Grackle Go

I then uploaded the second file to be tested

Second file uploaded

First document

The details of the file are shown at the top of the report

Scan results details

Then the report gives the grade of the report, alongside the number of passed, warned, and failed.

Grade B means that the document requires review, but passes most of the requirements, typically reports minimal errors, and may contain several cautions

B grade with 5642 passed, 1 warned and 8 failed. 3 errors with font not embedded

There are 2 pages in which the fonts are not embedded causing 3 failures for each font

No warnings or failures on the ISO and Natural Language sections.

Error - alternative description missing for an annotation

There is an annotation that is missing an alternative description.

Error - invalid use of a "L" structure element in "L"

There is an invalid use of an “L” structure element in “L”. This issue occurs when list structure in a PDF does not meet the expected hierarchy because the list items are not nested correctly.

Error - "DisplayDocTitle" entry is not set

The “DisplayDocTitle” entry is not set (to true) so that the document title is not displayed in the top bar and the filename is shown – it should be the document title on display.

Errors - PDF/UA identifier missing, XMP metadata missing in document, and title missing in document's XMP metadata

The PDF/UA identifier is missing, which means that the PDF does not have the required metadata tag showing that it complies with the PDF/UA (Portable Document Format for Universal Accessibility) standard – this should not be set unless the document passes all the tested criteria.

The XMP metadata missing in document, means that the overall language needs to be set for document.

The Title missing in document’s XMP metadata, means that a meaningful title has not been entered in the Title field of the document.

Second document

The details of the file are shown at the top of the report

Scan results details

Then the report gives the grade of the report, alongside the number of passed, warned, and failed

B grade, 8687 passed, 1 warned, and 6 failed

Grade B means that the document requires review, but passes most of the requirements, typically reports minimal errors, and may contain several cautions.

No warnings and 3 errors in the fonts

No warnings and no errors

No warnings and 1 error in document settings, and 1 warning and 2 errors in metadata

The issues are as follows

No warnings and 9 errors of fonts not embedded in pages

There is 1 page in which the fonts are not embedded causing 3 failures for each font.

Error - "DisplayDocTitle" entry is not set

The “DisplayDocTitle” entry is not set (to true) so that the document title is not displayed in the top bar and the filename is shown – it should be the document title on display.

1 warning, PDF/US identifier missing, 1 error XMP metadata missing in document, and 1 error Title missing in document's XMP metadata

The PDF/UA identifier is missing, which means that the PDF does not have the required metadata tag showing that it complies with the PDF/UA (Portable Document Format for Universal Accessibility) standard – this should not be set unless the document passes all the tested criteria.

The XMP metadata missing in document, means that the overall language needs to be set for document.

The Title missing in document’s XMP metadata, means that a meaningful title has not been entered in the Title field of the document.

Site preferences

Please feel free to display our site, your way by finding the preferences that work best for you. We do not track any data or preferences at all, should you select any options in the groups below, we store a small non-identifiable token to your browser's Local Storage, this is required for your preferencesto persist across pages accordion be present on repeat visits. You can remove those tokens if you wish, by simply selecting Unset, from each preference group.

Theming

Theme
Code block theme

Code theme help

Code block themes can be changed independent of the site theme.

  • Default: (Unset) Code blocks will have the same theme as the site theme.
  • Light 1: will be default for users viewing the light theme, this maintains the minimum 7:1 (WCAG Level AAA) contrast ratio we have used throughout the site, it can be quite difficult to identify the differences in colour between various syntax types, due to the similarities in colour at that contrast ratio
  • Light 2: drops the contrast for syntax highlighting down to WCAG Level AA standards (greater than 4.5:1)
  • Dark: Syntax highlighting has a minimum contrast of 7:1 and due to the dark background differences in colour may appear much more perceivable

Motion

Motion & animation

Motion & animation help

  • Default (Unset): Obeys device settings, if present. If no preference is set, there are subtle animations on this site which will be shown. If you have opted for reduce motion, smooth scrolling as well as expanding and collapsing animations will no longer be present, fading transtitions and micro animations will still be still present.
  • None: All animations and transitions are completely removed, including fade transitions.

Links

Underline all links

Underline all links help

  • Default (Unset): Most links are underlined, with a few exceptions such as: the top level links in the main navigation (on large screens), cards, tags and icon links.
  • Yes: Will add underlines to the exceptions outlined above, resulting in every link being underlined

Text and paragraphs

Font size (main content)

Font size help

This setting does not apply to the site's header or footer regions

  • Default (Unset): Font sizes are set to site defaults
  • Selecting Large or Largest will increase the font size of the main content, the size of the increase depends on various factors such as your display size and/or zoom level. The easiest way to determine which option suits you best would be to view this text after clicking either size's button
Letter spacing

Letter spacing help

  • Default (Unset): Default letter spacing applies
  • Increased: Multiplies the font size by 0.12 and adds the sum as spacing between each character
Line height

Line height help

  • Default (Unset): all text has a minimum line height of 1.5 times the size of the text
  • Increased: all text has a line height of twice the size of the text
Line width

Line width help

  • Default (Unset): all text has a maximum line width of 80 REM units (this averages around 110 characters per line)
  • Decreased: all text has a maximum line width of 55 CH units (this averages around 80 characters per line)
Paragraph spacing

Paragraph spacing help

  • Default (Unset): The space between paragraphs is equivalent to 1.5 times the height of the paragraph's text
  • Increased: The space between paragraphs is equivalent to 2.25 times the height of the paragraph's text
Word spacing preference

Word spacing help

  • Default (Unset): No modifications to word spacing are present
  • Increased: Spaces between words are equivalent to 0.16 times the font size
