Printing advice-I got size wrong for printers

[Cathy]

Sorry to have to keep asking everyone but I could do with some advice

I sent off two of my sunset pictures to Loxley and they very kindly called to tell me my image is too small not enough DPI and it also has banding ?

 

I am hoping to resend the images but have decided to just do one until i get it right. The size asked for was 18x9 inches.

 

 

The image i sent has this info in photoshop

 

Pix dimension 78

5400

2525

 

45.72cm

21.38cm

Res-300

 

They have asked that i send it 300 DPI with 1MG per inch   on the longest side.

So can you tell mw What is banding?

How do i find or make my image 1 MG on the longest side

you can get banding in photoshop if you play with your curves or levels too much.  it's strips or steps of color where it should be a smooth gradient.  you usually see it in skies.

What software are you using...?

In Photoshop for a print, I use the crop tool set on the settings bar to the size of the print and at 300dpi. This creates a huge file but is really what the printers need to get the best quality. Obviously, this has to be done before the original is re sized at all.

I use photoshop and Lightroom but mostly Photoshop.

Thank you for info on banding!

I did play with the image as it was a late sunset and was dark so yes I did edit it.

 

I have googled and I think the problem is the top one that said Pix dimension.Mine is only at 78.0mg but the raw file was way up at 74.2Mg so this may have been the problem.

I am going to send it with the large file and give them a ring to see if it has worked.lol!

Cathy - when you 'save' an image do you check Photoshop is saving at 300 dpi?

 

If not sure check:

Image /  

Image size

and make sure the document size / resolution is set at 300

 

Photoshop will leave the setting at a previous set resolution so if it was changed to 72dpi and you haven't realised?

Colin it is set for 300.

I am wondering if I sent them one I was trying to reduce in size for Facebook?

That top line of Pixel Dimesion looks wrong and I have no idea how it got to be so low lol!

Anyway sent them up one image a large file and called to ask them to check.i was told that they looked fine so fingers crossed it comes back ok.

Prints arrived back from Loxley and I am so delighted with them I took two to my local framer shop to be mounted and framed!

Can't wait to pick them up next week :)
