Unique black and white workflow
We offer a specially developed printing process for black and white images which automatically converts the images into what are known as Duplex images. The black colour is refined with an additional grey, which intensifies the depth of the image and eliminates annoying colour casts.
Please convert your images for the Duplex method using one of the following methods in Photoshop:
- For an RGB image, select → Image / Adjustments / Hue/Saturation / set saturation to -100.
→ Result: More depth/details, as a 3-channel image is calculated
- For an RGB image, select → Image / Mode / Grayscale
→ Result: Less depth/details, as a 1-channel image is calculated
- For a CMYK image, select → Image / Mode / Grayscale
If you want a saturated black, we recommend converting the black and white images into CMYK. Your black is composed in 4 colours, making it more saturated and stronger.
Black and white images based on colour systems (RGB or CMYK) tend to have a colour cast.
This can be counteracted by reducing saturation. The images (RGB only) are converted using our unique Duplex method.
If you would prefer a more open, grey black, we recommend converting the images to 1-colour black and white in Photoshop. 1-colour black has a more greyish look when printed and is less saturated than a black and white image in CMYK.
