Don't know if this is even possible, but am sure you all do. I have a file that I created in Flexi- it has some bitmaps and some vector stuff and text. Need to send this to a printer who wants it to be a 300 dpi jpeg. Saved the project from Flexi as a jpeg and sent her that...she says it's only 72 dpi. Changed the ppi to 300 (because it's the only number I could find that said "72") in the bitmap section of design central-she says it's STILL a 72 dpi jpeg. How do I make this thing a 300 dpi?
To complicate matters, I have photoshop, but don't have a clue with that, my skills with that include opening the program and importing a file and you guys helped me "lasso" something last week, which , by the way, worked wonderfully and saved my rearend!

Take it into Photoshop and reset the DPI. You then need to "Resample"

Export it from flexi as an EPS file. I realize there are bitmaps among the vector, but don't worry about that. Open it in Photoshop... It will prompt you how big you want it before it opens. Set the resolution to 300 & open it. Then hit file-save for web - & set the "settings" to the right of the preview to JPEG High. Hit OK. Email that image. Good luck Beth.

I may be missing something here, but usually a request for a specific dpi is all about the actual quality of the image.
if you have such low quality that pixels are evident, then you will be asked for a higher dpi file.
for most practical purposes, this request means find a better quality image, or start over a make the image again at a higher resolution.
Once an image exists as a lower then desired quality, you can look at any square pixel & tell your software to divide all the pixels into 4 pixels, or 9 pixels... or 16 pixels... but if it was a black pixel, now you have 4 black pixels that still make a big square of black.
Interpolation capability exists in photoshop & other programs, so in a curving line made up of black square pixels meeting white square pixels... when you cheat the resolution to a higher number as described above, you can get 4 pixels out of each one, but 3 of the 4 might still be black & the 4th corner of each one becomes white if the software can detect that this is probably what you want, based on trying to make that curving line a smoother "line" between black and white... with less stair-stepping of square pixel corners. This "interpolation" will usually be able to add some small improvement to the resolution through "guessing". but I still consider it cheating because it is a band-aid solution.
Anyway, the best solution is to always design at a high resolution to begin with.

Doug is right on, you can't make silk out of pigskin LOL. However if you have the original pictures you used you can scan them at a higher resolution, or if it is vector art converted you can convert it at a higher resolution than you originally did. Bill

If I'm reading Beth right, then I agree with Doug. If you start with an image letter-size at 72 dpi and resample to 300, you'll get a postage stamp. Or maintain your original dimension, and you'll have a pixelated mud-pie. It's the same principle as reduction/enlargement. So always start big.

Beth, Is this for a client of yours? Is he requesting you to send "artwork" to a printer?
If so, tell them that artwork charges will apply and then redesign if necessary. AND charge $90 per hour to do it.
I tell the customer that the files I use are in a native format in a proprietary program. Anything else needs to be charged for.
And what Doug and others says is true. You can't just click on a 72dpi and turn it into a clean 300dpi image. It's as if each pixel needs to explode 4 times to make up the size difference.

most printers use TIFF files, a JEPG is a lossy file. In its compression it throws away bits of information away. As Doug says you cannot take a 72 DPI and Make it 300 from a bit map image. Now DPI stands for Dot Per Inch which is a line screen, that is different that PPI or pixels per inch (web or monitor). It may be confusing but they are different. Most printing reqires only 150 DPI only the high gloss fancy Magazines reqire the 300 dpi. Different kind of paper can only handly certain DPI or dot patterns with out filling in, if the paper is really course like newprint 96 DPI is all that is reqired. all of this information is for process printing, not spot color. 72 PPI is best for web design
Go back to the source vector image resize and In Photo shop open a new file and it will prompt you for the size and DPI or resolution then place or import the vector image in at the size you wanted then save as a TIFF. If you have a low resolution image to start with you will have to go to the source of the Picture or what the customer supplied, I find most of what the customer supplies is Junk!
Michael the "save for web" is just for that, web images.

Thanks Chris. I didn't know they had vector files there. I also forgot I still had some credits after purchasing some files for a logo design a few months ago... so I'm downloading some cool vector scrolls right now. Nice stuff!
