4K iris images: 4096 × 4096 pixels at 300 dpi
Every finished iris leaves IRISORA at 4096 × 4096 pixels and 300 dpi, cut out and carrying an alpha channel. Here is what that means for print.
- 4096 × 4096 pixels
- 300 dpi metadata
- Square, no distortion
- Alpha channel for layout
What 4096 × 4096 pixels mean in print
At 300 dpi that is roughly 34.7 × 34.7 cm. Larger formats simply use a lower dot density: a wall piece is viewed from further away, so fewer dots per centimetre are enough.
What matters is that the resolution comes from real image information rather than upscaling a small file.
Square for a reason
An iris is round. A square output encloses it completely, without cropping or distortion, and leaves your layout free to go portrait, landscape or square.
Cut-out and alpha channel
The file contains the cut-out iris with a softly fading edge and transparency, so it drops onto any background without a second mask.
Resolution is not everything
- A sharp 4K file needs a sharp capture – pixels do not replace focus
- Structure work affects the impression more than raw pixel count
- A clean edge is more visible in print than extra megapixels
- 300 dpi is generous for normal viewing distances
An honest resolution claim
IRISORA does not advertise an 8K export. The final iris is 4096 × 4096 pixels – that is the number you can plan and argue with.
Frequently asked questions
- How large can I print a 4K iris?
- About 35 × 35 cm at 300 dpi. Larger wall pieces work at a lower dot density because viewing distance grows.
- Is the file cut out?
- Yes, with a soft edge and an alpha channel.
- Is there an 8K export?
- No. The final output is 4096 × 4096 pixels.
