Why won't my SCT file display in the browser?

No browser supports it — browsers render PNG, JPEG, GIF, WebP, AVIF, SVG and BMP, and nothing else. The file downloads instead and needs an image editor.

What opens an SCT file?

Photoshop imports it, as does ImageMagick. Converting to TIFF makes it far more portable.

Will converting change the colour?

If you convert CMYK to RGB, yes. For a print archive, convert to CMYK TIFF to preserve the colour values.

Host an SCT file and share it as a link

Put a Scitex continuous tone image online at its own address — from high-end prepress systems.

You can host:

Drop your SCT file here

Any other file works too — up to 25.0 MB, or 100.0 MB for a whole site

Free to use. Your SCT file is live at your-name.99helpers.site in about ten seconds.

What is a .sct file?

SCT is the continuous tone format of Scitex prepress systems, which dominated high-end print production before desktop publishing took over. Files are CMYK, uncompressed and very large — built for drum scanners and imagesetters rather than screens.

What people use SCT files for

Legacy prepress archives
High-end print production files
Scanned artwork from Scitex workflows

What opens a SCT file

How to host a SCT file

1
Drop your SCT file in
Drag it onto the box at the top of this page, or click to choose it. Files up to 25 MB are supported, and nothing is uploaded until you publish.
2
Pick an address
Type a name and we'll tell you straight away whether it's free. That becomes the link: prepress-scan.99helpers.site
3
Publish and share
Create a free account — that step exists so the file is yours to update, replace or delete — and the link is live within seconds.

The same three steps work for any file — see how file hosting works on 99helpers.com.

What happens when someone opens the link

The file downloads. It's a prepress format from a world that predates the web entirely.

Why host a SCT file instead of emailing it?

Print archives occasionally need retrieving, and hosting makes a file available to whoever can open it.

Worth knowing before you publish

Photoshop opens SCT and can save to TIFF, which is far more portable.
Files are CMYK — converting to RGB changes the colour, which matters for print archives.
Uncompressed, so files are large; most exceed 25 MB.
