What is AutoInk™ plug-in?
What Is It?
AutoInk™ is a plug-in for Adobe® Acrobat® software. The plug-in provides a set of Acrobat tools (pens and highlighters) for easy annotation of PDF files using pen input. The software is capable of converting handwritten ink into text or sticky notes. Use these tools to write notes, draw, doodle, fill form fields and highlight document content.The plug-in uses smooth inking provided by Microsoft operating system and feels very easy and natural to use with a pen input. It can be also used with any other pointing device such as mouse. The Acrobat's standard "Pencil" tool is designed for a mouse input and does not utilize a pen support that comes with latest operating systems. As the result, AutoInk provides a much better user experience.

Functionality Overview
Write, Draw or Doodle
Use 5 different pen tools (black, blue, red, green and white) to write or draw anywhere on the document. Adjust pen thickness and color for a custom appearance. Easily erase ink with a top of the pen or use a special "eraser" tool.
Highlight Document Content
Use 5 different adjustable highlighters to markup document content (text, images, graphics). AutoInk can create both regular text highlighting (anywhere on the page, not just over text elements) or semi-transparent inking annotations. Adjust highlighter's width, color and transparency for a custom appearance. Here is sample of document marked up using various highlighters:
Highlight Text By Search
The plug-in can search for user-specified words and sentences and automatically highlight them in the document. Text can be highlighted with a single color or using 20 different automatically assigned colors (each search term is highlighted with a different color).
Annotate Images with Transparent Highlights
Use transparent highlighters with adjustable transparency to draw on top of images and engineering drawings.
Fill PDF forms
Write right on top of the text form fields using pen input. Easily convert ink into a text with a click of a button. The plug-in performs a handwriting recognition using latest Microsoft technology and automatically fills form fields underneath.
Convert Ink To Text
Easily convert any inking into either native PDF text, text box annotations or sticky notes. Use advanced recognition settings and custom word list to improve recognition results. Control font style, color and title case of the output text.
Optionally convert handwriting into a text box annotation or a sticky note.
Save Inking As Pencil Annotations or PDF Line Graphics
The plug-in allows saving inking either as pencil annotations or directly as PDF line graphics(for improved performance).
Flatten Ink Annotations
Easily flatten ink and other annotations to preserve their content and appearance. All interactive content and inking annotations will be converted into native PDF graphics that cannot be easily changed.
Insert Blank Pages
Conveniently insert blank or notebook-style pages with a single mouse click to make room for more inking. The plug-in automatically creates new pages based on dimensions of the current page.
Adjust Ink Appearance
The plug-in provides full control over the color, thickness and transparency (for highlighters) of all inking pens.
Show/Hide Inking by Pen Colors
Show/hide pen inking annotations based on pen color. For example, show only inking in red color and hide the rest. Unlike regular Acrobat filtering by color, this operation is persistent and allows making ink hide/show annotations in the PDF file.
Lock/Unlock Inking by Pen Colors
Lock/unlock pen inking annotations based on pen color. For example, unlock only inking in red color and lock the rest. This make it easier to edit pen inking in a specific color while preserving the rest.

«Absolutely outstanding! The product is perfect. My company has a host of remote sites, and most of our document work is virtual. That doesn’t work well when we need signatures (lots of faxing and scanning). I am going to recommend that the company invest in tablets and your .pdf software, given its incredibly broad functionality. »
