PS CS 5.5, Mac OS 10.7.2 -- two problems

[Brinnoven]

Have just purchased a new 27" i7 iMac which came with Mac OS X Lion (10.7.2) pre-installed and upgraded to Photoshop CS 5.5. At the same time we also upgraded to SilverFast 8 so we could use our Epson Perfection 3200 Photo with the new equipment.

It's generally working well and produces great scans, but I seem to have two consistent problems which I haven't been able to resolve:

1. When scanning into PhotoShop using the SilverFast plug-in the images are coming into PhotoShop at 72 dpi resolution regardless of the settings in Silverfast. (i.e. I'm currently scanning a lot of line art illustrations at 100% size/600 dpi which end up in PhotoShop at 833% size/72 dpi). Obviously it's easy enough to fix in PhotoShop, but it's an extra step we shouldn't have to be doing.

2. The other problem is that when using SilverFast as a stand alone application it crashes every time when it tries to save the scan file to disk.

Has anyone else seen this?

The only other observation I would make is that SilverFast 8 on the new iMac is actually noticably slower than SilverFast 6 was on our old G4 Mac ruinning 10.4.11...

1.
The DPI is a page preset in Photoshop.
That is nothing that could be fixed in SilverFast.

2.
Please make sure you have full access to the intended folder.
In case you are using OSX please try repairing the disk permissions using the disk utility.
Also try saving to a differnet location like the desktop.


Kind regards,

Thanks for the response.

Ah -- OK. Presumably this is something that has changed between PhotoShop CS2 and PhotoShop CS5.5? When using SilverFast as a plug-in with PhotoShop CS2 on a G4 Mac running 10.4.11 images scanned using SilverFast as a plug-in come into PhotoShop at the resolution defined in SilverFast.

Can I ask if you're absolutely sure about this? When I use SilverFast as a standalone application which saves the files to disk and then open the files in any application they always open at 72 dpi resolution. To me, this looks like a SilverFast problem.

I have some more information about this.

When I scan images in colour or greyscale they save OK when using SilverFast as a stand-alone application.

Every time I scan in 1-bit mode SilverFast crashes when trying to save the Scan File.

This is 100% repeatable and consistent.

Kind regards,

Hi,
When scanning i.e. a picture where the original is 16,85x11,16cm with a wanted output 20,0x13,25 the results comes out in 83,33x55,21 with 72 ppi while it was wanted wit 300 ppi (when opened in Adobe Photoshop Elements 10)

When the same is done on in this case a windows xp PC it comes out in a correct manner.

This PC is a new Dell Vostro with Windows 7 Professional 64-bit.

The Silverfast program bought from you is Silverfast 8.0 Epson Perfection V600 bought within the last week. - The shortcut on the desktop shows "SilverFast (64bit)"

Dear Willi

Can I ask if you're absolutely sure about this? When I use SilverFast as a standalone application which saves the files to disk and then open the files in any application they always open at 72 dpi resolution. To me, this looks like a SilverFast problem.

We are sure about it. Your scanned files have an absolute number of pixels for each side, how every application displays each file is something that can not be controlled from SilverFast, it has to be specified in each application or operating system.

Dear Ib

The same applies to your original question

Cheers

We are sure about it. Your scanned files have an absolute number of pixels for each side, how every application displays each file is something that can not be controlled from SilverFast, it has to be specified in each application or operating system.

Let me try explaining what is happening in a different way.

Here is an example. I set the scan parameters manually.

I set the resolution in SilverFast to 300 dpi. Output is set to 5 inch x 4 inch.

This (correctly) produces a file that is 1500 x 1200 pixels.

When Silverfast saves the scan as a TIFF file it correctly sets the ImageWidth and ImageData TIFF metadata tags to 1500 and 1200. But SilverFast incorrectly sets the Resolution metadata to 72 dpi.

The Resolution metadata should be set to 300 dpi (the resolution set in the SilverFast Scan dimensions window). SilverFast is not doing this. May be it not correctly reading the value of the resolution value set in the Scan Dimensions window.

So when PhotoShop (or any other application) open the file it is wrongly displayed as a 20.8 inch x 16.7 inch 72 dpi file.

UPDATE. I have just experimented with letting the SilverFast WorkFlowPilot complete a scan. This is very strange -- the Resolution metadata value is now getting saved correctly and files are opening at their proper size (even when I change the resolution manually).

I will monitor this to see if it keeps working.

I tried that but I am still having the same issue. No matter what resolution I scan in, PS CS5 reads it as 72 dpi. The file size does get larger with increased resolution
Did you find any other solutions?

It all worked fine yesterday. Scanned at 300 and it showed 300 in PS CS5. Thanks

Brinnhoven is right on this.
I have exactly the same problem when using SilverFast 8 with conversion to 72dpi in Photoshop. This was not a problem when I use Silverfast SE 6.6. With SilverFast SE 6.6I can import from SiverFast and it maintains the correct size. My SilverFast SE 6.6 still works on this machine so I can compare how it works vs SilverFast 8 side by side. The new SiverFast 8 knocks the dpi down to 72 and makes the dimensions much larger once you get back to Photoshop. This is not a photoshop setting it is something different with how SiverFast 8 interfaces with photoshop (as evidenced by the comparison of SE 6.6 scanning from the same version of photoshop with all the same settings). It is annoying and you should fix this bug not just say that it is a photoshop problem. I like many of the new features of SilverFast 8 and would rather use it but if this is not fixed I will have to revert to SE6.6.
I am using a Mac OS 10.6.8, Epson Perfection 3200 Photo, and Photoshop CS 3.

I am having the same issue. Tried the route suggested above to no avail. I also scanned a document with Adobe Acrobat and Photoshop opened the file at the resolution I used for the scan. (NOT 72). This is obviously an issue in the scanning software. Please help me resolve this. I am using your most recent upgrade to Silver Fast 8 and my Mac software is up to date also. Thank you.

Dear customers,

Like my colleague already wrote this is only a matter of metadata handling.
It does not influence the scanned resolution itself.

Our current investigation did not show any greater issue here.
All images had the intended size.
It seems that only the embedded resolution tag is not read correctly.
This does not have any impact on the image itself.

We have forwarded this to our product management and will fix this in a later version of SilverFast.

kind regards,
Arne Ketelhohn
