Vector Print quality VS Rasture and something I didn't realize.

A Tip for New Sign Makers (That Took Me 7 Years to Learn)

Most of you experienced sign shops already know this, but I thought I’d share it for the newbies—because it took me 7 years to figure out.

I’ve had my Mimaki CJV150-130 for about 8 years now. Like many, I started in the school of hard knocks (still enrolled, by the way). I do most of my work in Photoshop but constantly bounce back and forth with Illustrator.

Early on, I would create a layout in Illustrator, bring it into Photoshop for tweaks, and then save it as an EPS—thinking I still had that crisp vector quality from Illustrator. I didn’t.

Just because something saves as a vector format doesn’t mean it remains a vector. Once Photoshop rasterizes the image, saving it as an EPS doesn't magically restore the vector quality. What you get is what I call a "vectorized-looking raster file"—lol.

The result? My prints were often grainy, semi-transparent, and just didn’t have the punch I expected.

So to any newcomers: keep your vector work in Illustrator when possible. If you need to use Photoshop, know what’s being rasterized and when. It makes a huge difference in print quality. Always try to Save from Illustrator.

Hope this saves someone a few years of trial and error!

PDF format has been great for me. Why not just print directly out of Illustrator to your Mimaki? Tweaks were photographic imagery in Photoshop?

Me: Well, we're going to have to charge a design fee to vectorize it in order to blow it up and still be high quality
Client: What do you know! We do have a vector file!

you have customers that know what a vector version is? Most of the time I ask that they have no idea what I'm talking about. So I explain it.... then they send that same rastered bitmap as a pdf, or eps.... can't tell you how many times I've gotten an actual illy file with vector in the name and it's still just the same bitmap image. :roflmao:

Definitely prefer vector, but most people I deal with have no idea what that is. I'm ok with raster images so long as the person making it accounts for the end use and uses appropriate resolutions. Sometimes I'll have to match type on some raster image and I'll raster the text @1200 DPI just so I know it'll be good for printing.

So I explain it....
Someone on here gave me the idea of asking for the file they can't open.
But yeah, folks resaving the same png as pdf/eps/svg, it's old hat by now. If I've asked twice, you get what you deserve.

They'll have every excuse in the book why they can't find what you need, but it really boils down to laziness on their part. Ahaa........ once you tell them what it'll cost to re-create the file into a vector format....... PRESTO........ is this what hat you need ?? :banghead:

Quit buggin' me
Hah, I just went through this, in reverse, late (real late) last night. Had a customer send pdf files and did not embed the bitmaps or send them in the packet. Files would open in Illustrator with missing image file errors and low-rez previews of the missing images for placement. When I opened them with Reader the bitmaps were all there at the right resolution. Illustrator 29.7.1 could not find them. I pushed all the link/re-link/go-to-link buttons with no luck. I ended up placing the PDFs into a new blank file and rasterized them. Printed just fine.
