Graphics guys, whats up with this

well the units must be aligned in an isotopicular collinear fashion before exported into dpi for maximum accuracy and definition.

300 is overkill. 100 should be just fine for a biz card. try exporting/save as a gif file and then adjust the size before printing.

When your image is open goto IMAGE/Image Size, change the document size to the print size you want, not the Dimensions of the image.

hahahahaha

LOL, don't do much printing do you??? That has to be the most wrong answer I could ever imagine in my life.

First off 300 is not over kill for a biz card. You want your DPI to be twice the line screen of what you are printing. If you are planning on sending it to a print house to be printed, they are probably printing at about 300 line screen, so you would actually want 600 dpi image. If you are just printing on your ink jet, 300 dpi is fine, anything over 180 will do well on an ink jet (ink jets don't go by line screen). You can not go up in DPI only down, so if you have an image that is 3 x 2 at 300 DPI you can not make it 3 x 2 at 600 DPI.

Secondly, converting your image to a GIF is about as stupid a thing as you could possibly do, you just took your image from Millions of colors to 216 colors and changed it from RGB to Index Color Profile.. and just destroyed your image.

When changing the size or DPI of an image in Photoshop, make sure you DO NOT have "Resample Image:" checked, or it will ruin your image. Uncheck that, and put in the size that you want the image, and it automatically tell you what the new DPI will be. You don't want anything under 150 dpi for an Ink Jet, you can go under, but you'll be losing quality.

Also, a biz card is 3.5 x 2, so you're missing a 1/4" in the length.

The only reason why I can think it is printing too big is that you are either wrong about what size you have it set at, or you have your print settings set to print at a percentage higher than 100% or fit to page. Because there is no reason for Photoshop to print at any other size than what you have set in your Image Size dialog box, no matter what the DPI is.

Wow, this is too profound.

Well Said!!
You need to make sure you set the Document size, not the image size!

The only thing i will add is, it depends on where you are getting the file printed, my printer requires the image in CMYK not RGB, 300DPI, .jpg and also requires a 1/4" Bleed around the image.

Wheres Graphic Dude when you need him? JK looks like plenty of knowledgable people here

Check your printer settings.

hehe, im noob about this stuffs...please elaborate
