In this chapter, I'm going to go over proofing our document, printing our document, preparing a print ready PDF to send to a commercial printer. Also, preparing a screen PDF that you can put on a website and that can be downloaded quickly and also archiving the job and thinking about the next issue. What parts of this newsletter can we repurpose for next months issue and the month after that, and the month after that so that every time we repeat this job, it gets that bit easier, that bit quicker? To begin we are going to look at Preflighting. Preflighting is the process of looking at the document and checking for any errors based upon a list of rules that you can determine. You may have noticed that throughout the course of putting this document together, down here it might have a certain times said, 3 errors, 2 errors or however many errors and that's because certain things that we have done in putting this document together triggered an error based on a preflight profile.
The preflight profile that we have been using thus far has been the default basic preflight profile. But we are going to determine our own preflight profile that is going to be a little bit more rigorous than that and here is how we can do it. I'm going to come to Define Profiles. We see that we have the default Basic and we also have this one here Newsletter that I have created. And to create a profile you simply click on the +symbol and check the relevant boxes for all of things you want the Preflight profile to check.
I am going to just delete that one and we'll take a look at the one that I created earlier, the Newsletter profile, we can expand all of these different areas. General is nothing more than a description of the profile. Simple text description of it. Links we want to be notified if any links are missing or modified. In the Color group I have chosen to check this one Color Spaces and Modes Not Allowed to just sort of we are notified if any spot colors are used. Since this is a newsletter, this is going to be printed in cyan, magenta, yellow, and black, presumably.
I have also chosen to be notified if any Overprinting or any Registration that may have been applied. Frankly, it's unlikely, but it will be good to know about if that has happen by mistake. Images and Objects. This one is important, Image Resolution, Color Image Minimal Resolution. Now the minimum that you choose is going to depend upon your printing circumstance, but I have set this to be 300 pixels per inch. That's the optimum resolution for high quality print. And I'll so chosen differing resolutions for the Grayscale, although I think I want to make that the same as the color 300 and the 1- bit Image Resolution. This necessarily should be as close as possible to throughout the resolution of your painting device.
Frankly, it's no consequence to us because we don't have any 1-bit images. Non-Proportional Scaling of Placed Object, so this will notify as if any image has been scaled non-proportionally. It's been stretched or squeezed. Minimum Stroke Weights, we can set that away if we want the stroke weight to be. 0.125 of the point and the Text, this one is important. Overset Text, we want to definitely be notified about that, if all of that text isn't fitting onto the page. We want to be notified of Missing Fonts or any Non-Proportional Type Scaling.
So having chosen all of those criteria, now to use them, I'm going to go ahead and click Save, because I did make one change to that. Then click OK to check the document against that profile. I'm going to come to the Preflight panel. Preflight is on, I'm going to change it from Basic to Newsletter. Now as I do so, you will see down here change from No errors to 2 errors. So it gives us a list here of what the errors are. I'm going to expand that.
First error is an Image resolution problem. I'm going to expand that, and it tells us that's the name of the image, this is the page on which it occurs and I happen to know it's that one right there, but if I didn't know that, I could click on this and it would jump me to that place in the document. More information about the problem. So we set Minimum Image Resolution at been 300 pixels per inch. The Problem is that the Effective Resolution of this is only 256. We are going to let it go. It's close enough. It's good that it warned us, but 256 is still going to work okay. Now if that was 72 or 96 or something, a lot lower than it currently is, then we would have to have act upon it. We would have to find an alternative image, maybe go back to the source image that perhaps at some point had been scaled down and we are working with the low-resolution version of the source image. But we would have to take some appropriate action. In this case since it is in the ballpark of our required resolution, we can let that one go.
Our second problem, Non-Proportional Scaling. I'm going to click on that link and we see right there, aha, so a picture here, looks like it's been stretched a bit. Now if I take my Direct Selection tool and click on that, we can see that indeed we have some Non- Proportional scaling going on. 18% and 19.6%. So I need to set that back to being proportionally scaled and to do this we'll split the difference I think. Here we'll go to 18.5 and making sure that this is an unbroken chain. If I now just click down in the vertical scale, that will also become 18.5 and we are now reduced to 1 error, the one that we already know about, the resolution on the dog image.
So that is process of defining a Preflight Profile and then checking your document against that Preflight Profile.
