Creating a 10ft x 2ft banner??
 

Hi there,
need to create a 10ft by 2ft banner. I had planned on doing this in photoshop. have done a conversion check and its 304.8cm by 60.96. only prob is that photoshop will only take a measurement up to 254 nevermind 304!! now im not sure how to go about creating the image?? any advice would be so good. thanks very much

not sure why you're not able to get bigger,
The limit seems to be at 416.666" x 416.666'' (1058.33cm x 1058.33cm)

I just created a new doc
1200'' x 24'' or 304.8cm x 60.96cm

Also the text limit stops at 1000pt

this is on photoshop v7

Thanks - im on Adobe Photoshop 7 too.

im going File, New, im typing in 304 and i get the message "A number between 0.01 and 254.00 is required. Closest value inserted."

is this what youre doing?

Yes, what other selections do you have.
I updated my last post to show what my max limit is

what do you mean by selections? (sorry!)

Many printer drivers have a "Banner Print" option, although it's often not that name. Look in the page layout area. This will work MUCH easier and faster than having Photoshop crunch through 20 square feet of data.

Colour mode.
resolution.
just wanted to see if yours is the same as mine

Although none of it should make a real difference.
The only thing that comes close to giving me that limit number
is
resolution at 250 pixels/inch

I assume your going to get a print shop to print this for you,

If you still have problems and the doc is just text, then I think if you do as big as you can and save the file as an eps, the print shop should be able to take it to its print size with out too much loss, I would check with them in any case as to what they need.

general large format printing
 

Most printers that i have used for large format work usually ask for artwork at 1/4 size of print size. They use their software rips to scale the image up to size with minimal loss of quality.....also doing artwork at that 1/4 size tends to lead to much time saved while doing the artwork. Save your artwork as eps as well....that keeps them happy as it will fly through the RIP unlike jpeg etc.

see attachment for the guide that i have used for a couple of years with great results.....always chat to printers about such matters !

thanks for all the tips. so i think ill get in touch with the printers and find out if i can do it a quarter of the size, sounds a much better plan, and then save it as an .eps in Photoshop. thanks very much

Hey savage, Off topic.

That was my first pdf file opened in Adobe reader 7 as an inline document in safari. Very nice.

Photoshop dpi limits
 

Photoshop 7>
Maximum height or width is 3000px

Photoshop CS<
Maximum height or width is 30000px

And still for some jobs thats still not big enough. e.g. recently we had a job that had a final print size of 7x30 feet.

PS7 maximum file size 30,000px in either dimension

PS CS 300,000px in either dimension (PSB format enabled in preferences)

g,

Have you gone into PSCS Preferences > File Handling and enabled the large file format option?

I'm sorry, px is pixels per inch. ?

so 30,000 is only 39.97"

Am I missing something Here :confused:

Hi Mark,

Pixels is pixels, so to speak. DPI is resolution (pixels/inch). You could have a 30,000px image sized to 300 inches at 100 DPI or 100 inches at 300 DPI. To avoid confusion it becomes easier to think in total pixels needed for a given size and resolution. (That was the PS7 limit, PSCS is 10x as large.)

Yes silly me , my mistake,

So what prints at 3,000 dots per inch ? (PS7)

I know mags do about 300
And newspapers around 150 (uk)

Well imagesetters normally print at 2400 or 3600 DPI but the maximum file resolution data they use is 1200 DPI. Almost all 8-32 bit files are printed on lithographic screens which use LPI (Lines Per Inch). File resolution for LPI printiing is 2 x LPI. That's why the typical Photoshop file is prepared at 300 DPI as a 150 LPI is common for high quality color printing.

Here's a page which has a bit more info.

Welles , Thanks for that

There is no limitation in the maximum résolution of the file to be printed...

For a line-art job, the usual résolution is 1200 dpi, but for a high-quality job you can use 1800 or 2400 dpi or more if you want: the only "limitation" is that there is no use for a picture to have a resolution higher than the resolution of the imagesetter (in a Tiff-It file, the line-works "part" is 2400 dpi).

For a contone job, the resolution of the picture has to be 2 X LPI for printing with a screen equal or under 133 lpi. For printing with a screen higher than 133 lpi, the resolution of the picture has to be 1.5 X LPI, that's enough: for a 150 lpi printing, you only need to have 225 dpi pictures.
Using higher resolution for contone pictures makes loss of place on the HD and loss of time while working with the pictures (from scanning to film burning, including modifications with Photoshop, burning CD to send to the printer, or ripping the file for the imagesetter). It also allows to over-size the pictures in the XPress ou ID image boxes (with a 300 dpi picture and a 150 lpi screen, you can over-size to 130%), but everybody knows that it's better to keep the pictures at 100%...
Using very high resolutions (for example 600 dpi or more) for contone pictures adds a down-sampling of the picture while ripping and makes some loss of details in the picture.

As stated by myself earlier

(change the "or"s should of been "and/or"s)

These are Photoshop's MAXIMUM file dimensions not print size.

The only thing dpi has to do with it is the print size e.g.
So at 300 dpi in this would give you a maximum print size of

• 100x100 inches in PS 7

• 1000x1000 inches in PS CS

at 150dpi

• 200x200 inches in PS 7

• 2000x2000 inches in PS CS

But when you are printing large banners and the like, you do not need such a high dpi e.g.

• Billboards and bus sides are usually only 50 dpi.

• Presentation displays are usually 100 - 200 dpi.

Because you are further away from the print.

Do it in pro
 

Hello

I have done 48 sheet billboards and point of sale banners in photoshop.

Just do them at a percentage of the final size, ie 50% and get the printer to run it out at the correct size ie 200%. As long as you do the resolution (dpi) to compensate - (ie if the final banner is at 150 dpi - do the artwork 300 dpi)

Sometimes you have problems with scratch disks filling up etc, but if you have enough hard disk space, it is normally OK.

I'm not sure why you would want to enter this into Photoshop as cm... why not just enter is as inches? Less confusion.

I had no problem entering 120 inches by 24 inches. At 300 pixels/inch that is going to be a 741.6 MB file! And that's before you add anything to it.

Personally I wouldn't do something like this in Photoshop. It's not what it was designed for. If you use a vector program like Illustrator, you can work with a reduced file and then output it at the full size with no degrading the output.

A second alternative would be to use a page layout application in conjunction with Photoshop, or what ever.
