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.
Is It Smooth?
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.
How It Differs From Acrobat's Pencil Tool?
The plug-in is designed for writing with a pen and uses very smooth inking interface found in Windows 7, Windows XP and Vista. 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.
Supported Platforms
The plug-in is designed to provide a native support for new handwriting recognition, inking and pen features available in Windows 7, Windows Vista and Windows XP Table PC edition. The software can be also used with regular XP with extra download.
What Do I Need?
You need a Windows Tablet PC computer running Adobe® Acrobat® or you can use a regular Windows PC with a pen input device such as a Bamboo Wacom tablet. Although, the plug-in works even with a regular mouse, it is recommended to use a pen writing device for a smoother and more natural 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:
Fast Text Color Coding
Use "Highlight Text" toolbar to quickly color-code selected text using 5 different adjustable 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).
Use Acrobat's "Comments" panel to navigate, search and work with text highlights created by "Highlight by Search" function:
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.

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).

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.

«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. »
