What is Lambda C-type Printing?

A Lambda c-type print is a digital print produced using Durst’s Lambda machine – a photographic printing machine that uses three lasers (RGB – red, green and blue) merged into one beam to produce digital c-type prints on light-sensitive silver halide materials. Exposed paper is then traditionally wet’ processed using photographic chemistry, in much the same manner as traditional photographic prints produced using negatives with an enlarger in a darkroom.

Using this process, we are able to print your images full colour or black and white in sizes up to 1219 mm (48 inches) in width and up to the length of an entire roll – which is a massive 1,968 inches.

To increase the archival stability of your images, our c-type processor includes three wash tanks rather than the standard two.

Why Should I Choose Lambda C-type Prints?

Lambda c-type printing is the highest quality digital c-type printing available and uses the renowned Durst Lambda processor to produce prints that combine a traditionally archival process with all of the benefits of digital control. Digital file information (the image) is passed directly to photographic paper using a system of lasers (rather than LED’s, which are used by some digital c-type printers). The Durst Lambda c-type printer produces an image with a higher PPI than commonly used LED printers, such as The Durst Theta or ZBE’s Chromira.

Through this process, we are able to achieve ultra sharp photographic digital C-type prints with true continuous tone, crisp edge-to-edge printing and absolutely no distortion.

We only use the highest grade archival materials to produce your Lambda C-type print and carry stock of Fujicolor Crystal Archive papers in traditional Matte, Gloss, Super Gloss, Pearl and Velvet finishes alongside transparency materials (Fujiclear and Fujitrans – also commonly known as Duratrans or backlit transparencies).  Each paper offers the tactility of a traditional photographic print but with all of the benefits of additional control associated with a digital photographic printing process.

Because we don’t believe that photographic printing should be anything less than the highest quality, we only offer one level of service – our very best.

What is your turnaround time for Lambda C-type prints?

As with our all of our printing services, we aim to turnaround print orders within 48 hours of your order being confirmed by a member of our Client Support Team. Turnaround times may be longer when a test print is required. Please speak to us to confirm turnaround times on large print orders or when working to tight deadlines. 

How do I send you my files, negatives or transparencies?

We’ve made it as easy as possible to upload your digital files to us and have provided you with several options – simply choose which one suits you best.You have the option to use our upload form, Email us, or send your files by Hightail, or FTP.

After you have sent your digital files and details to us you will need to contact us to arrange payment and confirm your order details. We will not proceed until we have been contacted by you.

Of course, if you would rather provide your files on a CD, DVD or memory stick or have negatives or transparencies to produce prints from, you can send these to us at:

Genesis Imaging

Unit 1, Hurlingham Business Park,

Sulivan Road,




or drop off your files in person – we even have free off street parking.

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. 

You can also download our Lambda Profile to see a fairly accurate softproof preview of the printed output on your screen (if your monitor is properly calibrated). We calibrate our Lambda Colour Profile frequently so please download the latest version from the link above.

After downloading the profile of your choice simply drop it into the following folder on your mac – / Library / ColorSync / Profiles folder or the / Users / username / Library / ColorSync / Profiles folder. Then restart Photoshop, open your image and choose from the top menu Edit > Assign Profile. In the dialogue box that appears select the Lambda profile from the Profile drop menu. This temporarily assigns the Lambda profile to the image without converting colours to the profile space. You can permanently assign the Lambda Profile to your image by choosing from the top menu Edit > Convert to Profile and then from the dialogue box that appears choose the Lambda Profile from the Destination Space Profile drop menu.

For PC users the path to place the Lambda profile in is WINDOWS system32 spool drivers colour folder.

If you have any questions about colour profiles please feel free to call and one of our friendly and knowledgeable staff will be pleased to help you.

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.

What is the maximum print size for Lambda C-type prints?

We can produce Lambda C-type prints in any size up to a maximum of 50 inches in width and, in theory, up to an entire roll in length – which is a massive 1,968 inches.

What is the difference between a Lambda print and a Giclée print?

Both Lambda and Giclée prints are brilliant photographic prints and both are produced by the digital process. Lambda c-type prints have the tactile look and feel of a traditional photograph while our Giclée prints can be produced on a diverse range of tactile coated or uncoated papers. Our Durst Lambda printer uses lasers (RGB – Red, Green and Blue) to expose photographic material, whereas the Giclée process physically lays ink on paper or canvas. Both our Lambda and Giclée prints are produced on archival quality papers. The real differences boil down to individual preferences; it’s all about the “look and feel” of the final print and whether it conveys the image as you want it. Unfortunately, the real differences cannot be shown on a website, but our team are happy to explain the process in more detail and show you examples – please contact us to arrange your visit.
