Question about DPI

[Honkyharris]

Morning everyone,

    I've been working on putting together my artwork designs and I have a question regarding quality. I understand that you can vectorize an image to preserve quality as the size is blown up, but what about just making it at high quality in the first place? If I make my artwork in photoshop with a canvas using a 300dpi quality will that be good enough to send to somewhere like mamemarquee and have them print it?

Thanks guys,
Honkyharris

  If you are creating text and other original elements within a 300 dpi project, yes it will hold up for printing.   The problem becomes apparent when you import elements into your image that are from lower resolution sources.  You tend to have to make them so large (transform) that they look terrible.  Basically you have to create everything in your 300 dpi composition yourself OR use only import hi-res images or vector elements and you will be ok!!

The man speaks the truth.  Don't grab stuff from Google image and toss it into your 300dpi creation unless they are really really big.  Most anything you see on the web is 72dpi.

Imagine taking a magic marker and write your name in tiny print on a balloon...then blow up the balloon...and you will see where it is stretched beyond recognition...the term is interpolation.

You can alway take large and shrink to small, but NEVER small to large.

  Come on guys, that can't be true, every time I watch CSI they have those cool filters on their computer that can blow up images, like tiny little security camera shots of license plates.  They hit that magic button and BAM, focus!!  Where can I find me that plug-in!!?   

[garnerb350]

I just want the plug-in where everytime i say anything...like for example "Can you pass the butter?"  The opening bit from any The Who song blares loudly....." "YEEEEEEEEEEEEEEEAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHUUUUUUUUUUHHHHHH!!!!! "

Thanks for the replies guys. I don't plan on adding anything but my own stuff so that answers my question!

Not to hijack, but somewhat along the same question lines of DPI......

If I had a large piece that needed scanned in pieces and then stitched back together for touchup work in Photoshop or Illustrator, what would be the recommended scan rate ? (without going rediculously high of course due to file sizes)

And if using something like Photoshop or Illustrator what's the power hungry PC components in regards to large higher resolution files? (i.e. RAM, CPU, Video Card, etc)
I would hate to scan this thing and then find out my PC can't handle the file sizes or whatever that I've scanned it at. (making it dog slow scenario)

[Necroticart]

for scans 300 dpi or higher is recommended as for the file size it depends on what you are scanning as for a raster program I can't recommend the 64bit version of photoshop enough If your messing with large images like sideart now as for vector if the image can be vectored go for it as some images are more difficult to reproduce than others

[Billy_Goatfeet]

 Yeah I would agree that 64 bit system with Photoshop (64) would be helpful but for most people that isn't going to happen.   I was thinking it would be great if you would work in a proxy mode when composting your panels together for ease of CPU drain.  Meaning working with a lower resolution version of your image and then when it is finished you could replace the low resolution proxy with the high resolution scan.  I have never worked this way in Photoshop but it is something you can do in After Effects and most professional compositing applications.  Maybe someone else here has tried that workflow?

  No matter what if you are going to work with high res scans and stitch them together it will be a hog on your machine.  It just comes down to how bad it is and wether it is manageable or not.  Give it a go!

ya I wish photoshop had a proxy mode it would definitely be a welcome feature as for 64bit processing it will become more main stream sooner than you think with the 4GB ram limitation of the 32bit operating systems it really is a must for anyone working with multimedia applications especially HD video editing and encoding also Cudu is a real help in that department cutting down rending time substantially.

[Billy_Goatfeet]

  Isn't the 64 bit version of Vista/Xp also burdened by a 4 gig ram ceiling?  How about Windows 7?   It would be nice to be able max out the ram, that makes a huge difference for sure.  I thought 32 & 64 bit had the same issue, maybe I am wrong.   Are most apps running in 64 bit now?  That was the other issue for me not going 64 bit.

[Necroticart]

actually the 64 bit version is capable of 128 GB of memory even though no board supports that much ram as for windows 7 it is the same way. as for apps most of the new adobe line are 64 bit capable now except illustrator and I believe all major 3d apps support it also. the only real hindrance is old plugins as most are written with the limitations of 32 bit processing in mind the only other quark is the apps running in 32 bit mode windows only allots 2 GB of ram but that is only really noticeable in pro apps or games the pros definitely out weight the cons keep in mind in  windows 7 microsoft has stated they are able to raise the ram limitation if they see fit to do so
