Le zoom 100% ne correspond pas à la réalité

[Baptiste226969048uza]

Bonjour,

Je cherche à corriger un problème. 

Quand je règle le zoom sur 100 % en travaillant sur mon format A4, celui-ci n'est pas correct. Si je veux avoir les bonnes dimensions, en taille réelle, il faut que je règle le zoom sur 94,5 %, ce qui est assez pénible. Est-il possible de résoudre cela ?

Merci ! 🙂

There have been some recent discussions of this issue (getting "100% zoom" to represent the exact page size on the screen). You don't say whether you are on Mac or Windows, but I believe both can be adjusted so that the zoom level is accurate.

This involves setting your screen scaling to a precise value within InDesign. Unfortunately, this simple value is not accessible via a Preferences field, but can be set using a script.

Install this script, and then run it. Set your screen resolution to a value that will produce an exact size for 100% zoom — you can do this by measuring the width and calculating the different setting needed.

/*
* Set a custom display resolution

*/
var mm = app.generalPreferences.mainMonitorPpi.toFixed (2);
$.writeln(Number(mm))

makeDialog()
var cRes, ckBox;
function makeDialog(){
var theDialog = app.dialogs.add({name:"Display Resolution", canCancel:true});
with(theDialog.dialogColumns.add()){
staticTexts.add({staticLabel:"Custom Resolution:"});
staticTexts.add({staticLabel:"Use System Setting: " + mm + " "});
}
with(theDialog.dialogColumns.add()){
cRes = realEditboxes.add({editValue:Number(mm), minWidth:100});
ckBox = checkboxControls.add({checkedState:false, minWidth:150});
}
if(theDialog.show() == true){
cRes = cRes.editValue;
ckBox = ckBox.checkedState;
setCustomRes()
theDialog.destroy();
}
}

/**
* Discription
* @ return value
*
*/
function setCustomRes(){
if (ckBox) {
app.generalPreferences.customMonitorPpi = 72;
app.generalPreferences.useCustomMonitorResolution = false;
} else {
app.generalPreferences.customMonitorPpi = cRes
app.generalPreferences.useCustomMonitorResolution = true;
}
app.activeWindow.zoomPercentage = 100;
}

Hi,

Thank for your answer, I don't really understand why I need a script if I have to change my screen resolution, which I prefer not to touch.

However, if I try, where can I find this script ? I have never used this feature.

Thanks

Save it to a file called 100percent or something with file extension .jsx

Any text editor will do

Just make sure the actual file extension is .jsx

Hi @Baptiste226969048uza , just to clarify, normally you shouldn’t need my script to get a 100% view that matches print output, but it looks like the problem occurs in some cases when you change the InDesign UI scaling preference—I’m on aMac still using CC2021 so I can’t test, but the script doesn’t actually change your monitor res, it just changes how InDesign adjusts its scale based on the monitor resolution reported by the OS.

[Baptiste226969048uza]

Hi

I did not change InDesign UI scaling preference. 

I specifiy that I'm using Windows 11 Pro.

I tried and this windows appears : what does 144 mean ? It is a ratio or something ? I understand that it has to do with the resolution but I don't know how.

Thank you

Thank you

[rob day]

144ppi is the display resolution reported to InDesign by the OS, which InDesign uses to calculate the 100% Print View.

In your case, for whatever reason 144 is not right. Try entering 136 and see if that gives you the accurate 100%print view (144 x .945 = 136).

[Baptiste226969048uza]

After few tests, 126 is approximately the correct value.

I tried to calculate this ppi with this : https://www.sven.de/dpi/

My screen resolution is 2560 x 1440 with Windows and mesures 15,6 inches. It gave me 188.28 PPI and I entered it, but the result is wrong. I don't understand why.

[Baptiste226969048uza]

After few tests, 126 appears to be aproximately the good value.

I tried with this website to calculate it (https://www.sven.de/dpi/  )  but the result - 188.28 - is incorrect when I enter it.

OMG It actually works although I paste your code in Text Edit (macOS) as plain text and save as .js because .jsx cannot be runned. Thank you very much.
