What are Duratrans?

Backlit transparencies (also known as Duratrans or Fujitrans) are photographs or images printed on a translucent-base material, ideal for displaying on lightboxes.

We print both Duratrans (which have a translucent base) and Duraclears (which have a transparent base and are commonly used in lightboxes with diffusers) using our Lambda c-type process – which is archival, and similar to a traditional photographic process but with all of the benefits of digital control.

Lambda technology uses three lasers (RGB – red, green and blue) merged into one beam, your Images are exposed to photosensitive transparent film  before being traditionally ‘wet’ processed in much the same manner as traditional photographic printing. To increase the archival stability of your Duratrans, our Lambda printer includes three wash tanks rather than the standard two.

Using this process, we are able to achieve true continuous tone, ultra sharp photographic images with crisp edge to edge printing and absolutely no distortion. Duratrans can be produced from digital files, negatives and transparencies in full colour or black and white, up to 1219 mm (48 inches) in width.

Why should I choose Duratran printing?

Because our Duratrans are produced using the same Lambda C-type process they are archival, durable and suitable for gallery exhibitions and interior displays.

Duratrans are ideal for displaying in lightboxes as the translucent-base of the material used for printing allows some light to pass through from behind, illuminating and enhancing your work.

Which colour profile should my work be saved as?

Our preferred choice of colour profile for the best possible photographic printing with our very carefully controlled ICC workflow is Adobe RGB (1998), although we do accept files in other colour profiles- if in doubt, please do not hesitate to give us a call on 020 7384 6200. 

Which file format should my images be saved as?

As a general guide for colour prints on either our Giclée or Lambda printers, your images should be in RGB, any layers flattened and preferably saved as a Tiff file (.tif) with LZW compression. This will maximize the quality of your image and also keep the file size down. Other file formats are acceptable such as a layered tiff or photoshop document (.psd) but these will have an inherently larger file size. Jpegs (.jpg) are fine for smaller prints but because of their image lossy nature it is not recommended that you save any files in this format. Images shot as in-camera Jpegs are once again mostly suited to small to medium prints. Naturally we are also happy to accept RAW camera files.

Once again, please do not hesitate to get in contact if you have any questions about file formats for photographic prints.

How do I know if my file is the correct size for the print I require?

We check all files prior to printing and will call you should we notice any loss of quality at the print size you require.

As a rule of thumb – the larger the print size required, the larger the file size must be. There is however some leeway with the image resolution or dpi and how our Giclée or Lambda printers deal with this. For instance: if your image file is approximately 20MB at 400 dpi it will make an excellent print at A5 size. The same 20MB file will still make an excellent 10×8″ print at 300 dpi, and a very good 16×12″ print at 200 dpi. If you are in any doubt, go for a higher resolution for the print size required. Please contact us if you need any further assistance with file sizes for photographic prints.
