Logo quality in title block degrades when produce pdf

[jdicker85]

Hi,

I've noticed a problem over several years in relation to high quality picture files of logos with super clear edges and then I import it into my title block to use for jobs for various builders.  The problem is that the logo degrades a lot when I print it to pdf and gives a very unprofessional result with blurry or jagged edges to the logo or logo writing. 

I use adobe acrobat for pdf printing and the logos are high resolution in either gif, png, or jpg format and the format doesn't seem to matter.

Does anyone have an idea of how to solve this or the best way to have logos in the title block?

Thanks,

Jeremy

What Revit version?  Insert PDF instead of JPG.

That's pretty bad.  I wonder if is not something else going on here.  Post the Image File and the Titleblock RFA.  

[jdicker85]

Please see attached title block rfa.  and the original image file.

Its weird as it doesn't seem to matter what image file or version of revit in the past so I thought maybe I'm loading it in wrong or something.

[jdicker85]

My version is REVIT LT 2021.1.2

In your experience is do you use a pdf of the logo to import into the title block?

[ToanDN]

Prior to 2020 I use a PNG, not JPG. Since 2020, I import PDF because it Revit let me adjust DPI of PDF when imported from 72 to 600. For logos which are generally small, I choose 300 or even 600 depends on the detail of the logos 

[jdicker85]

It doesn't give me the option to choose pdf files under the import image option so I don't see how I can use a pdf logo.

[jdicker85]

Thankyou, the logo I post here and tried is a PNG. How do I import a pdf into the rfa to use as a logo? I don't get that option when trying to import an image.

[ToanDN]

Sorry I realized Revit LT can't import PDF.  I will take a look at your logo in Revit 2019, I don't have 2021.

[barthbradley]

Would you consider white non-transparent background JPG? 

[jdicker85]

Thankyou , I tried the non transparent jpg version and its still degraded but just degraded differently.

[jdicker85]

In Revit it looks fine, the  problem seems to be when it gets turn to a pdf.   I guess the fault could be the pdf printer rather than revit.

See view of title block zoomed in and snipped within revit.

[ToanDN]

Try this. It is a modified PNG, still with transparency.

Use the Revit LT Export to PDF give better result out of the box.  If you choose print to PDF, edit the PDF printer preference and increase raster output DPI.

Attached are a PDF exported from Revit 2022 and a PDF printed to AdobePDF with High Quality settings.

I don't get any distortion on my end. Hardcopy or PDF. Looks good in that screenshot too. Not sure what you see that I don't. But your original with the transparency background was FUBAR.  

Can you Import PDF. Got one of those too, but I pulled it because I thought you said you couldn't use PDF with LT. 

[jdicker85]

Thankyou for your help!   Do you get any distortion printing a pdf  via acrobat or whatever program you use from Revit if you do it that way?

I have attached a snip I've done of the original logo on the left, then the degradation of the other 2 from printing via pdf.  The middle was the non transparent jpg and the right side was the transparent png.  so this should show an easy comparison to how much worse it gets for me.

In my Revit LT 2021 I can't import pdf picture files and I also can't export to pdf.  Maybe if I update to 2022 there's increased functionality for those things there.

[jdicker85]

I tried your modified png and it ended up the same as the middle image in the comparison screenshot I posted. thanks

[barthbradley]

That middle one is the one I sent printed from Revit? Looks good to me. For a vector software that is.  Probably looks better on a sheet too. Not zoomed in so tight.  What's the sheet dimensions of the logo?  2"x 1 1/2" or so with Image scaled 0.065?

You need to edit the PDF printer and increase the quality.  Look at the PDF I attached below and compare the quality to yours.

[jdicker85]

Oh my god, why did I not realise there was an easy setting for this earlier!

thankyou so much.  It is much better with that simple change.  This is what I needed to do 5 years ago lol.

Is it normal for the document to take over an hour to create the PDF when printing to Adobe PDF? I tried to print 8 sheets in this manner, legal size, and it is taking over an hour so far. Saving as Microsoft PDF takes less than 10 seconds. But I'm getting the distorted logo issue.
