TWAIN Driver - Colortrac

TWAIN

For many users of image management software or any software that relies on using a scanner the TWAIN interface will no doubt sound familiar. The Colortrac SmartWorks TWAIN driver provides a simple way to directly control a SmartLF SC or SG Series wide format scanner from inside applications that are compatible with the TWAIN 1.5 standard and other specialist software that supports TWAIN connected scanners.

SmartWorks TWAIN installs itself as a TWAIN plug-in module and is automatically recognized when the application supporting TWAIN is started. Help and guidelines for operation of Colortrac Twain can be found here.

Why TWAIN or ISIS?

Functioning ISIS and TWAIN scanning interfaces offer very similar scanning experiences for the operator but they differ considerably in how they are provided. ISIS is highly regulated to control the quality of the driver and every ISIS driver is certified by EMC who hold the rights to the ISIS scanner connection standard. Certification is not free which ensures higher standards but it also means that TWAIN as free and open-standard software is more widely accepted and more popular within the majority of scanning software providers and developers.

TWAIN Online Help

Colortrac TWAIN is aimed primarily at 3rd-party software developers who can now use the Twain v1.5 specification to quickly build basic scan tool interfaces for the Colortrac SmartLF SC scanner into virtually any software application. Colortrac TWAIN permits the user to control resolution, color mode and scan size. It will not support the higher Twain functions such as optical character recognition (OCR) and color management. All file formatting and image enhancement is handled by the host application.

For non-developers Colortrac TWAIN has been tested with the following software applications. Batch scanning is not supported.
