EPS exports wrong size

Recommended Posts

Hello there,

 

I've imported a vector graphic into affinity, the original size was 142x142px with 96dpi. I've converted it into cmyk color mode and adjusted the canvas size to 4x4cm 300dpi. However, when I export the file as an EPS file, Affinity generates a 152x152px image in 72dpi.

 

PS: Great program, can't wait for it to be out! :)

I have been able to repeat this.

 

1. Create graphic in Illustrator, sized 80mm X 80 mm

2. On import into Affinity, the artwork dimensions change to 60 mm X 60 mm.

 

Just out of interest, that scaling difference seems to match 96 versus 72 dpi.

Does the file format EPS per se really deliver a true page size and resolution at all? At least resolution sounds weird according vector data, doesn't it?

 

Also, as far I experienced with vector objects: neither page size (cm) nor resolution (dpi) gets always transported when converted like its origin but usually doen't do any harm. Many applications have issues to interpretate dimensions (cm) and resolution (dpi) of an EPS file.

 

So I wonder, if @ Aurelio does indeed get any wrong, means low-res, jaggy, printed output with his exported Affinity-EPS mentioned obove.

No, the output is crisp, so its en EPS file for sure ;). I don't know if eps file format can contain any size information. It is just an annoyance when importing the file into an dtp program like inDesign or Scribus as you have to resize everything. As you can see in the attached screenshots, while importing the image file into Scribus (I no longer have inDesign installed on my machine to do some tests), it recognises an image file in 72dpi resolution. What concerns me also, is that it also is displayed as an RGB file, while it was set up as a CMYK file. I know that inDesign makes problems when trying to publish documents in the wrong color space or resolution. It would also mean that you had to convert vector files created in Affinity designer into a bitmap file in the right color space and resolution (in a program like PS) before being able to use it in inDesign etc.

 

I've tried again to create a sample image with the following specs in Affinity Designer:

W: 4cm

H: 4cm

Generic CMYK

I've exported the file as an EPS, TIFF and PDF file.

 

When importing it into Scribus i get following measurements:

EPS: size: 152x152px; colorspace: Unknown; 72dpi

TIFF: size: 472x472px (16,65cm); colorspace:CMYK; 72dpi (would be 4cm as 300dpi)

PDF: size: 113x113px; colorspace: Unknown; 72dpi

 

When importing it into Photoshop CC 2014 i get following measurements:

EPS: size: 152x152px; colorspace: CMYK

TIFF: size: 472x472px (16,65cm); colorspace: CMYK; 72dpi (would be 4cm as 300dpi)

PDF: size: 472x472px (4cm); colorspace: Generic CMYK (thats perfect)

 

I've attached the file if somebody whats to import it into inDesign perhaps and some screenshots.

Hope this helps!
