Print Guide
Preparing and sending your image file for printing
Managing colors
For best printing results, it is necessary to prepare your digital files following our guide and our suggestions. Our workflow is managed completely by the standars of Colour Management. All monitors, scanners, printers are calibrated regularly. There is an overall 5000K color temperature lighting in our studio providing color-accurate environment.
The essential point in preparation is working with a calibrated monitor. Use an external device (colorimeter) and suitable software for calibrating the monitor. The new monitor profile will be copied to the operating system by the software, so all graphical applications will show right colours throgh your monitor's profile. Make sure you do not change - even accidentally - the monitor's controls and settings after calibration! It is recommended to renew the calibration at regular intervals, at least in every six months.
Choose a system profile for your work. We advise using one of the following standard RGB colour profiles to your photographic workflow:
• Adobe RGB 1998
• ProPhoto RGB
• sRGB (in special cases only as sRGB gamut is limited)
Set the selected standard RGB profile as default in your photo applications and always include this profile when saving your image file!
Download the ICC profiles for soft-proofing within media details at printing page.
Never save these media profiles to your image file!
Always save backup copies of your original images (e.g. RAW, TIF) and the layered files (TIF, PSD). Don't use data compression like JPG, use lossless methods like TIF with LZW compression instead.
Manage your pictures in their own standard gamut (RGB system profile), do not convert the images to CMYK nor assign other profile, unless you have specific reasons to do that.
Resolution
Always set the resolution in print size: ppi (pixel per inch) the width or length of your image divided by the number of pixels
• 200-300 dpi below 0,5 m2
• 150-300 dpi between 0,5 m2 and 1 m2
• 100-200 dpi over 1 m2
• 100-200 dpi for canvas prints depending the print size
Sharpening
Sharpening the image for the print size in Adobe Photoshop:
• set to view the real printing size on your monitor (this is not the 1:1 size, because that's for 72 dpi)
• use the ruler tool (Ctrl+R) to show the real size in cm, mm or inches at the sides of the screen
• sharpen with the Unsharp Mask tool viewing your picture in real size, select smaller pixel radius and higher sharpening amount in %.
• (e.g. Printing size: 60x80cm - Unsharp Mask amount: 100%, radius: 0,5-0,7 pixels)
File format:
• We propose using TIF with LZW lossless compression for bitmaps
• You can use either 8 bit or 16 bit color depth both printed at the highest quality
• EPS, or PDF (Press Ready format) are the best for vector based or mixed type works, using RGB or CMYK system profiles
• Do not forget to save the system icc profile into your image file!
• Please contact us when you use not common file types or softwares.
