Best Practice Guidelines to add a non intrusive, high quality overlay on PDF File

The following are useful guides to adding professional and relevant overaly.

Keep it simple

Most often, it’s better to just go with the simplest and most evident presentation. Adding many visual details might end up messing with your overall design by adding up noise. For the most effectiveness, it is always best to include only one visual that communicates an idea immediately.

Match The Document Style.

In terms of look and feel, your added image or text content on PDF documents must look and complement with the document itself. Using the same styles, patterns as well as the font on the paper will surely create a harmonious whole document.

maintain consistency in size andposition

use semi transparent overlay in appropriate situations

It helps for transparency that will still leave information in view of the target , however it shouldn’t come in way of information in its entirety

Make Sure No Overlay Covers Critical Information

There’s one thing about overlays: if placed poorly, it has a huge possibility to cover your important content and leave it unreadable. Try to keep an open area where your added item can rest without getting into your content’s toes

Add Overlay to Multiple PDF Pages

Several PDF editors can superimpose a single overlay on all pages. As a result, this is an ideal way to Add a Logo to a PDF or to place a watermark, status, and similar labels.

When adding an overlay on multiple pages, it is important to check a number of first, middle and last pages once the process has completed as different page styles can make it impossible for a single position on one page to work for another.

Desktop PDF Software

The advantages of a desktop based PDF editor are that the positioning will remain precise throughout the entire document in the way you desired. Furthermore, you may also have more control over the positioning and transparency of an overlay, and can also place the same overlay on selected pages or more.

It is possible to place an image and text overlay on a single document or any document specified if the work-flow is set correctly.

Common Mistakes When you Add Overlay

If a PDF has a poorly designed overlay, it can easily render the entire document unreadable and may reflect poorly on the document’s creator. We detail some of the more common mistakes to avoid below:

Covering Important Information

An overlay should never prevent people from reading text where important content is placed. Always check that the pages have text content in the area where you wish to place your overlay so it doesn’t obscure the information.

Excessive Opacity on overlay

Watermarks can only truly fulfil their purpose when they are noticeable. Excessive opacity however, will mean the text below is illegible.

Image sizes too large/too small

This is more of an artistic mistake rather than technical but a large image will render a lot of pages unnecessary for viewing when the overlay itself dominates.

Using poor quality images for overlay

If a company logo or digital signature has come from a poor quality source it can instantly make an entire file look unprofessional. Therefore, always try and work from an original, clear scan of your signature or high resolution scan.

Not compensating for differing page layouts

Each of the pages is not always going to present itself in an ideal orientation to be a document that you can simply ‘drop’ an overlay onto. Different pages can include large tables, images, pictures or margins; it is always a good idea to check a number of pages within the document for suitability.

Too many elements in an overlay

A document doesn’t need to be covered with lots of overlays. Just add what is appropriate.

How to add Overlay without diminishing PDF quality

In order to achieve a good quality end product, we advise you to use the best source material that you possibly can in addition to a decent PDF editor. Good sources of material to include in your overlay will include high resolution copies of images as opposed to scans of those images. You should also keep logos at their best, and if the software allows, vector logos would be the best option when you come to Adding an overlay.

However the quality is not solely down to source material, it may also depend on transparency. Highly transparent watermarks will obviously not be seen whereas wholly opaque content will make underlying text illegible and therefore ineffective. This is the trick that most users struggle to master in their Add Overlay to PDF procedure.

Add Overlay for Watermarks

Watermarks are the most common use of the Add Overlay function. A PDF page can host some form of title to specify the documents purpose e.g.

• Confidential
• Draft
• Sample
• Approved
• Internal Use
• Copyright protected

Watermarking is essential as it lets the viewer and receiver know the context of the document even when it may be seen in a number of environments that the original author has no control over.

Add Overlay for Company Branding

The Add Overlay facility also offers companies with another way in which they can maintain branding on their documents without needing to redo them each time an update to their branding is available. A logo can be placed somewhere sensible on each document making them appear to have been retyped when it’s actually just been edited.

Add Overlay for signatures and stamps

When you apply Add Overlay for signatures and official stamps, placing the element correctly is essential. Make sure when adding these, that they aren’t covering essential parts of the document such as names and addresses. Always make sure you zoom in while placing it, and take note not to cover things like dates or instructions.

Add Overlay for Forms and applications

When forms and applications have already been filled out and have then been converted to a PDF, Add Overlay can be used to create ‘Completed labels’ this can apply to:

• Signatures
• Stamps
• Reference numbers
• Dates
• additional notes

Always ensure when adding a stamp to a form as an overlay, that it doesn’t obscure any other parts of the form.

Add Overlay for images and graphics

Pictures may also be inserted to the PDF as an overlay. Should you wish to include a graphic to a document, maybe a logo, diagram, picture or map then Add Overlay is the only means to insert this as the document would otherwise have to be re-typed.
