Side-by-side or overlay PDF diff driven by one engine that reads each file into a structured model — text, vector geometry, images, form fields, annotations — and compares the models. Moves show as moves, edits show only where they happened, and any PDF type works without picking a mode.

A mild, semi-soft cheese of whole cow milk, pasteurised (Trento also allows thermised), first made in the Val di Non in Trentino and named in 1955 by joining Fontina and Emmental. Mesophilic lactococci and rennet set the milk at 30–35 °C; the pressed wheels are brined and ripened one to two months in the cold, then usually coated with coloured wax.
No fixed amounts recordedDairy production; the regional sheets give temperatures and times but no amounts. Wheels weigh 8–12 kg (Lombardy) or 10–12 kg (Trento).

A mild, semi-soft cheese of whole cow milk, pasteurised (Trento also allows thermised), first made in the Val di Non in Trentino and named in 1955 by joining Fontina and Emmental. Mesophilic lactococci and rennet set the milk at 30–35 °C; the pressed wheels are brined and ripened one to two months in the cold, then usually coated with coloured wax. Made in 6 steps over 33 days – 2.1 months. The longest step, ripen cold, takes 30 days – 2 months (Regione Lombardia 2008) and runs at 4–10 °C (Regione Lombardia 2008). Selected lactic starter culture that includes mesophilic lactococci does most of the fermenting.
A cousin of Fontina made from pasteurised milk (or thermised, in Trento) with a selected culture, ripened one to two months. In a study of commercial cheeses, Fontal had a coated rind with no smear and a lower pH than raw-milk Fontina; two cheeses sold as traditional Fontal had a thin smear and a Fontina-like pH.
Name
Coined in 1955 from the names Fontina and Emmental
Acidity
pH 5.62–5.90 in commercial Fontal, against 6.01–6.46 in Fontina PDO
Size
Wheels 30–40 cm across with an 8–10 cm heel, weighing 8–12 kg
The milk is pasteurised in Lombardy and thermised or pasteurised in Trento, and thermised milk is not pasteurised milk. The cheese ripens cold, at 4–10 °C in the regional sheets.
Both regional sheets say Fontal began in the Val di Non in the 1960s–70s at a butter-making company, where a partner had introduced a Danish-type cheese whose whey was used to melt the butter blocks. After some years Fontal replaced it. Around the 1970s the large Trentino cooperative dairies took it up. The Lombardy sheet says it is now made industrially across Lombardy.
